Springer International Publishing AG Feedback Control Systems: The MATLAB®/Simulink® Approach
Book SynopsisFeedback control systems is an important course in aerospace engineering, chemical engineering, electrical engineering, mechanical engineering, and mechatronics engineering, to name just a few. Feedback control systems improve the system's behavior so the desired response can be acheived. The first course on control engineering deals with Continuous Time (CT) Linear Time Invariant (LTI) systems. Plenty of good textbooks on the subject are available on the market, so there is no need to add one more. This book does not focus on the control engineering theories as it is assumed that the reader is familiar with them, i.e., took/takes a course on control engineering, and now wants to learn the applications of MATLAB® in control engineering. The focus of this book is control engineering applications of MATLAB® for a first course on control engineering.Table of ContentsPreface.- Acknowledgments.- Introduction to MATLAB®.- Commonly Used Commands in Analysis of Control Systems.- Introduction to Simulink®.- Controller Design in MATLAB®.- Introduction to System Identification Toolbox™.- References.- Authors' Biographies.

Springer International Publishing AG Phrase Mining from Massive Text and Its
Book SynopsisA lot of digital ink has been spilled on "big data" over the past few years. Most of this surge owes its origin to the various types of unstructured data in the wild, among which the proliferation of text-heavy data is particularly overwhelming, attributed to the daily use of web documents, business reviews, news, social posts, etc., by so many people worldwide.A core challenge presents itself: How can one efficiently and effectively turn massive, unstructured text into structured representation so as to further lay the foundation for many other downstream text mining applications? In this book, we investigated one promising paradigm for representing unstructured text, that is, through automatically identifying high-quality phrases from innumerable documents. In contrast to a list of frequent n-grams without proper filtering, users are often more interested in results based on variable-length phrases with certain semantics such as scientific concepts, organizations, slogans, and so on. We propose new principles and powerful methodologies to achieve this goal, from the scenario where a user can provide meaningful guidance to a fully automated setting through distant learning. This book also introduces applications enabled by the mined phrases and points out some promising research directions.Table of ContentsAcknowledgments.- Introduction.- Quality Phrase Mining with User Guidance.- Automated Quality Phrase Mining.- Phrase Mining Applications.- Bibliography.- Authors' Biographies .

Springer International Publishing AG Correlated Random Systems: Five Different Methods: CIRM Jean-MorletChair, Spring 2013
Book SynopsisThis volume presents five different methods recently developed to tackle the large scale behavior of highly correlated random systems, such as spin glasses, random polymers, local times and loop soups and random matrices. These methods, presented in a series of lectures delivered within the Jean-Morlet initiative (Spring 2013), play a fundamental role in the current development of probability theory and statistical mechanics. The lectures were: Random Polymers by E. Bolthausen, Spontaneous Replica Symmetry Breaking and Interpolation Methods by F. Guerra, Derrida's Random Energy Models by N. Kistler, Isomorphism Theorems by J. Rosen and Spectral Properties of Wigner Matrices by B. Schlein.This book is the first in a co-edition between the Jean-Morlet Chair at CIRM and the Springer Lecture Notes in Mathematics which aims to collect together courses and lectures on cutting-edge subjects given during the term of the Jean-Morlet Chair, as well as new material produced in its wake. It is targeted at researchers, in particular PhD students and postdocs, working in probability theory and statistical physics.Table of Contents1 Random Polymers.- 2 Spontaneous replica symmetry breaking and interpolation methods for complex statistical mechanics systems.- 3 Derrida’s random energy models: from spin glasses to the extremes of correlated random fields.- 4 Isomorphism Theorems: Markov processes, Gaussian processes and beyond.- 5 Spectral properties of Wigner matrices.

Springer-Verlag Berlin and Heidelberg GmbH & Co. KG Probability in Banach Spaces: Isoperimetry and
Book SynopsisIsoperimetric, measure concentration and random process techniques appear at the basis of the modern understanding of Probability in Banach spaces. Based on these tools, the book presents a complete treatment of the main aspects of Probability in Banach spaces (integrability and limit theorems for vector valued random variables, boundedness and continuity of random processes) and of some of their links to Geometry of Banach spaces (via the type and cotype properties). Its purpose is to present some of the main aspects of this theory, from the foundations to the most important achievements. The main features of the investigation are the systematic use of isoperimetry and concentration of measure and abstract random process techniques (entropy and majorizing measures). Examples of these probabilistic tools and ideas to classical Banach space theory are further developed.Trade ReviewThis book gives an excellent, almost complete account of the whole subject of probability in Banach spaces, a branch of probability theory that has undergone vigorous development... There is no doubt in the reviewer's mind that this book [has] become a classic. MathSciNetAs the authors state, "this book tries to present some of the main aspects of the theory of probability in Banach spaces, from the foundation of the topic to the latest developments and current research questions''.

It contains mostly the author s research work on fuzziness of the last ten years and relies a lot on [10]-[32] and it is a natural outgrowth of them. It belongs to the broader area of Fuzzy Mathematics. Chapters are self-contained and several advanced courses can be taught out of this book. We provide lots of applications but always within the framework of Fuzzy Mathematics. In each chapter is given background and motivations. A c- plete list of references is provided at the end. The topics covered are very diverse. In Chapter 1 we give an extensive basic background on Fuzziness and Fuzzy Real Analysis, as well a complete description of the book. In the following Chapters 2,3 we cover in deep Fuzzy Di?erentiation and Integ- tion Theory, e.g. we present Fuzzy Taylor Formulae. It follows Chapter 4 on Fuzzy Ostrowski Inequalities. Then in Chapters 5, 6 we present results on classical algebraic and trigonometric polynomial Fuzzy Approximation.Table of ContentsABOUT H-FUZZY DIFFERENTIATION.- ON FUZZY TAYLOR FORMULAE.- FUZZY OSTROWSKI INEQUALITIES.- A FUZZY TRIGONOMETRIC APPROXIMATION THEOREM OF WEIERSTRASS-TYPE.- ON BEST APPROXIMATION AND JACKSON-TYPE ESTIMATES BY GENERALIZED FUZZY POLYNOMIALS.- BASIC FUZZY KOROVKIN THEORY.- FUZZY TRIGONOMETRIC KOROVKIN THEORY.- FUZZY GLOBAL SMOOTHNESS PRESERVATION.- FUZZY KOROVKIN THEORY AND INEQUALITIES.- HIGHER ORDER FUZZY KOROVKIN THEORY USING INEQUALITIES.- FUZZY WAVELET LIKE OPERATORS.- ESTIMATES TO DISTANCES BETWEEN FUZZY WAVELET LIKE OPERATORS.- FUZZY APPROXIMATION BY FUZZY CONVOLUTION OPERATORS.- DEGREE OF APPROXIMATION OF FUZZY NEURAL NETWORK OPERATORS, UNIVARIATE CASE.- HIGHER DEGREE OF FUZZY APPROXIMATION BY FUZZY WAVELET TYPE AND NEURAL NETWORK OPERATORS.- FUZZY RANDOM KOROVKIN THEOREMS AND INEQUALITIES.- FUZZY-RANDOM NEURAL NETWORK APPROXIMATION OPERATORS, UNIVARIATE CASE.- -SUMMABILITY AND FUZZY KOROVKIN APPROXIMATION.- -SUMMABILITY AND FUZZY TRIGONOMETRIC KOROVKIN APPROXIMATION.- UNIFORM REAL AND FUZZY ESTIMATES FOR DISTANCES BETWEEN WAVELET TYPE OPERATORS AT REAL AND FUZZY ENVIRONMENT.

Springer-Verlag Berlin and Heidelberg GmbH & Co. KG Derivation and Martingales
Book SynopsisIn Part I of this report the pointwise derivation of scalar set functions is investigated, first along the lines of R. DE POSSEL (abstract derivation basis) and A. P. MORSE (blankets); later certain concrete situations (e. g. , the interval basis) are studied. The principal tool is a Vitali property, whose precise form depends on the derivation property studied. The "halo" (defined at the beginning of Part I, Ch. IV) properties can serve to establish a Vitali property, or sometimes produce directly a derivation property. The main results established are the theorem of JESSEN-MARCINKIEWICZ-ZYGMUND (Part I, Ch. V) and the theorem of A. P. MORSE on the universal derivability of star blankets (Ch. VI) . . In Part II, points are at first discarded; the setting is somatic. It opens by treating an increasing stochastic basis with directed index sets (Th. I. 3) on which premartingales, semimartingales and martingales are defined. Convergence theorems, due largely to K. KRICKEBERG, are obtained using various types of convergence: stochastic, in the mean, in Lp-spaces, in ORLICZ spaces, and according to the order relation. We may mention in particular Th. II. 4. 7 on the stochastic convergence of a submartingale of bounded variation. To each theorem for martingales and semi-martingales there corresponds a theorem in the atomic case in the theory of cell (abstract interval) functions. The derivates concerned are global.

Book SynopsisVier von zehn oder jeder Vierte ...Ein Blick in eine beliebige Tageszeitung genügt: Statistiken sind ohne Zweifel ein wesentlicher Bestandteil unserer Informationsgesellschaft. Dennoch ist das Image des Faches Statistik denkbar schlecht. Die Diskrepanz zwischen offenkundiger Bedeutung und schlechtem Ruf beruht zum Teil auf dem fundamentalen Irrtum, die Qualität der statistischen Methoden mit der Qualität ihrer Anwendung zu verwechseln. Denn ob aus Unachtsamkeit, Unverständnis oder Unvermögen: In den Medien wird mit Statistiken allzu oft Des-Information statt Information betrieben. Dieses Buch lädt die Leser zu einer kritischen und amüsanten Irrfahrt durch falsche Schlagzeilen und unsinnige Interpretationen statistischer Ergebnisse in Tageszeitungen oder Zeitschriften ein.

Springer Fachmedien Wiesbaden Datenqualität in Stichprobenerhebungen: Eine verständnisorientierte Einführung in die Survey-Statistik
Book SynopsisDieses Buch beschäftigt sich mit den praktischen Fragestellungen statistischer Erhebungen (= Surveys) wie sie sich etwa in der empirischen akademischen Forschung, der offiziellen Statistik oder der kommerziellen Markt- und Meinungsforschung stellen: Wodurch unterscheiden sich verschiedene Stichprobendesigns? Wie sind sie praktisch umzusetzen (z. B. mit der Statistik-Freeware R)? Wie lassen sich die Daten- und die Ergebnisqualität beeinflussen? Wie kompensiert man Nonresponse? Wie können nichtzufällige Stichprobenverfahren und Big Data-Analysen im Zusammenhang mit den Aufgaben der Survey-Statistik funktionieren? Die Vermittlung des Methodenverständnisses wird unterstützt durch die verständnisorientierte Veranschaulichung der Basisideen. Diese Anschaulichkeit wird durch einfache und daher gut nachvollziehbare Beispiele gestützt. Für die vorliegende 3. Auflage wurde das Buch vollständig überarbeitet und inhaltlich unter anderem um die Betrachtung des Spannungsfeldes zwischen Survey-Theorie und -Praxis, die Grundlagen des Simulationsansatzes der Survey-Statistik und eine Auseinandersetzung mit den sich zunehmender Beliebtheit erfreuenden nichtzufälligen Stichprobenverfahren (inklusive den damit verwandten Big Data-Generierungsprozessen) erweitert. Jedes Kapitel wird zudem durch Aufgabenstellungen ergänzt, deren Umsetzung mit der Software R angeleitet wird.Table of ContentsVom Teil aufs Ganze – Einführung in die Stichprobentheorie.- Die Mutter aller Zufallsstichprobenverfahren – Die uneingeschränkte Zufallsauswahl.- Es geht auch anders – Weitere Schätzmethoden.- Zerlegen macht’s genauer – Die geschichtete uneingeschränkte Zufallsauswahl.- Nahe Liegendes gemeinsam erheben spart Geld – Die uneingeschränkte Klumpenauswahl.- Nahe beisammen und doch auseinander – Die zweistufige uneingeschränkte Zufallsauswahl.- Grenzt an Zauberei – Die größenproportionale Zufallsauswahl.- Welcher Zweck heiligt solche Mittel? - Die nichtzufälligen Auswahlen.- Anhang.- Literatur.- Sachverzeichnis.

Springer-Verlag Berlin and Heidelberg GmbH & Co. KG Aufgabensammlung zur statistischen Methodenlehre
Book SynopsisIn die 4. Auflage dieser Aufgabensammlung wurde eine in Aufgaben-Form gebrachte empirische Untersuchung über das Lotto 6 aus 49 aufgenommen, die auf der Auswertung von 1264 Lotto-Ausspielungen aus 25 Jahren beruht. Das Ergebnis lautet: Auch aus Sicht der Mathematischen Statistik gibt es rationale Tipp-Strategien. Sie lassen sich darauf gründen, daß die realen Lottospieler-Kollektive einem stark ausgeprägten Konsensverhalten folgen, das rationales individuelles Verhalten in der Form eines speziellen Gegen-den-Strom-Schwimmens ermöglicht. Allein die systematische Berücksichtigung einer einzigen kollektiv stark vernachlässigten Lottozahl - solche Zahlen werden als "Antikonsenszahlen" bezeichnet - hätte in den untersuchten Ausspielungen die mathematische Gewinn-Erwartung um ca. 30% erhöht gegenüber dem "Normal"-Wert von 50% des Einsatzes. Danach erscheint es hoch plausibel, daß Spieler, die ihre Tippreihen ausschließlich aus solchen "Antikonsenszahlen" bilden, sogar eine mathematische Gewinn-Erwartung erzielen können, die den Einsatz übersteigt. Ein Bereich solcher "Antikonsenszahlen" wird mit Hilfe eines statistischen Schätzverfahrens explizit bestimmt. Die praktische Nutzanwendung solcher Ergebnisse steht allerdings unter dem Vorbehalt, daß sich das kollektive Spielverhalten nicht signifikant ändert, z.B. weil es durch Informationen - wie die hier vorgelegten - gestört wird.Table of ContentsAufgabensammlung zur statistischen Methodenlehre und Wahrscheinlichkeitsrechnung.

Emerald Publishing Limited Statistical Methods for Categorical Data Analysis
Book SynopsisThis book provides a comprehensive introduction to methods and models for categorical data analysis and their applications in social science research. Companion website also available, at https://webspace.utexas.edu/dpowers/www/Trade Review.,." the first introductory text to cover, in a single volume, models and methods for discrete dependent variables, cross-classifications, and longitudinal data. A great strength of the text is the authors' informal yet sophisticated approach, which combines the discussion of general principles with illuminating and realistic empirical examples." -Roberto Mare, University of California, Los Angeles, USA "Teaching this book will be almost too easy. The prose is clear, the examples are well chosen, and the Web site provides practical details." -Michael Hout, University of California, Berkeley, USA An excellent job done by the authors. As with the first edition, Powers and Xie make the analysis of categorical data easy to understand. There are 7 chapters that are clearly written, begining with a review of simple linear regression, then going to loglinear models for contingency tables, models for ordinal and nominal dependent variables and models for event ocurrence (models for rates). The technical level is high enough to understand the theory behind the analysis and the interpretation of results. The inclusion of a new chapeter (ch.5) on multilevel models is very clearly written, and includes a short introduction to modern Bayesian modelling. Although there is not enough space for a complete introduction into this topic (which requires a high level of mathematical statistics) the authors refer to other books (like the one by Scott Lynch) for more detailed explanations (needed for a better understanding) of bayesian modelling in general. This book is a great addition to the library of students and scientists in areas like biology and sociology who want an explained compendium of (modern) techniques for analysing categorical data.

Oxford University Press Bayess Theorem
Book SynopsisBayes''s theorem is a tool for assessing how probable evidence makes some hypothesis. The papers in this volume consider the worth and applicability of the theorem. Richard Swinburne sets out the philosophical issues. Elliott Sober argues that there are other criteria for assessing hypotheses. Colin Howson, Philip Dawid and John Earman consider how the theorem can be used in statistical science, in weighing evidence in criminal trials, and in assessing evidence for the occurrence of miracles. David Miller argues for the worth of the probability calculus as a tool for measuring propensities in nature rather than the strength of evidence. The volume ends with the original paper containing the theorem, presented to the Royal Society in 1763.Trade ReviewReview from previous edition This is a high quality, concise collection of articles on the foundations of probability and statistics. ... The volume closes with an Appendix containing a very polished reproduction of Bayes's classic 'An Essay Towards the Solving a Problem in the Doctrine of Chances'. The Essay still reads very well, and it should be on every probabilist's 'must read' list. I feel quite comfortable saying something almost as glowing about this entire volume. I found this book very edifying and clear, and the debates and issues it encompasses are of great importance for contemporary philosophy of probability, statistics, and decision-making. I highly recommend this book to anyone with interests in these areas, and I commend Swinburne for putting together this neat little book. * Notre Dame Philosophical Review *Table of ContentsIntroduction ; Bayesianism - its scopes and limits ; Bayesianism in Statistics ; Bayes's Theorem and Weighing Evidence by Juries ; Bayes, Hume, Price, and Miracles ; Propensities May Satisfy Bayes's Theorem ; 'An Essay Towards Solving a Problem in the Doctrine of Chances' by Thomas Bayes, presented to the Royal Society by Richard Price.

University of Notre Dame Press Causality In Crisis
Book SynopsisIn the past fifty years statisticians and methodologists in the social sciences have developed and refined a family of closely related statistical methods for the study of social phenomena. While the value of such methods of analysis is universally acknowledged, their use has never been wholly uncontroversial. In 1993 prominent scholars from a variety of disciplines (social sciences, statistics, philosophy of science) gathered at the University of Notre Dame to debate whether causal modeling techniques old or new can really justify the drawing of causal conclusions on the basis of correlational statistical data. The resulting volume from that groundbreaking conference is Causality in Crisis? a comprehensive and sophisticated introduction to perhaps the most important set of issues confronting social scientific researchers in the 1990s and beyond.In the essays presented here contributors critically reassess the widely accepted view that statistical methods of analysis cTrade Review“This is a collection of essys by a distinguished group of authors that is a ‘must read’ for those with an interest in causal modeling.” —Piers Rawling, University of Missouri-St. Louis“[A]n attempt to set out what the problems with contemporary statistical methods are, what solutions are being proposed, and to open up the debates about their effectiveness to a wider audience.” —Social Studies of Science“. . . an exceptionally well written treatment of the current crisis in sociological methodology, with rich and lucid discussions, particularly by the editors, Vaughn McKim and Stephen Turner.” —Social Forces“This is a collection of essays by a distinguished group of authors that is a ‘must read’ for those interested in causal modeling.” —Philosophy in Review“The present book evaluates a striking new claim to provide the means for causal inference from statistical association. Readers can get a quick overview, or that plus a tutorial-like introduction to the statistical principles underlying the SGS algorithm, move on to discussions about the pros and cons of the method, and end with a deep understanding of the difficult issues that have surfaced here. And, what will prove most satisfying to the historically minded readers of JHBS, the endeavor is placed in a historical context that illuminates the nature of the issues at hand. It is refreshing to find an exception, an edited book with a consistent theme, an organization that encourages reading from beginning to end...Readers who take the time to do this will be rewarded with a new perspective on some old questions....the present book makes clear that the difficulties of inferring causation from correlational data are very much with us still. It is a pleasure to recommend this book to readers interested in opening the door to this fundamental issue in social science, whether in the form of the most recent statistically sophisticated approaches, or to the very first attempts to grapple with it.” —Journal of the History of the Behavioral Sciences,

John Wiley & Sons Inc Bayesian Statistical Modelling
Book SynopsisBayesian methods combine the evidence from the data at hand with previous quantitative knowledge to analyse practical problems in a wide range of areas. The calculations were previously complex, but it is now possible to routinely apply Bayesian methods due to advances in computing technology and the use of new sampling methods for estimating parameters. Such developments together with the availability of freeware such as WINBUGS and R have facilitated a rapid growth in the use of Bayesian methods, allowing their application in many scientific disciplines, including applied statistics, public health research, medical science, the social sciences and economics. Following the success of the first edition, this reworked and updated book provides an accessible approach to Bayesian computing and analysis, with an emphasis on the principles of prior selection, identification and the interpretation of real data sets. The second edition: Provides an Trade Review"This text is ideal for researchers in applied statistics, medical sciences, public health and the social sciences, who will benefit greatly from the examples and applications featured.

Journal of Quality Technology Sensibly organized for quick reference, Statistical Rules of Thumb, Second Edition compiles simple rules that are widely applicable, robust, and elegant, and each captures key statistical concepts. This unique guide to the use of statistics for designing, conducting, and analyzing research studies illustrates real-world statistical applications through examples from fields such as public health and environmental studies. Along with an insightful discussion of the reasoning behind every technique, this easy-to-use handbook also conveys the various possibilities statisticians must think of when designing and conducting a study or analyzing its data. Each chapter presents clearly defined rules related to inference, covariatTrade Review?This is a unique and effective contribution. Unlike some statistical books, this is a truly enjoyable read.? (Doody?s Reviews) "For the applied researcher who does much of her or his own data analysis, this book is a must-have. Even the applied statistician would benefit from owning a copy of this collection. It is certain that some 'rules' will be new, and the descriptions in the text can come in quite handy when one i trying to explain a concept to a non-statistician. In short, this collection of 'rules' is highly recommended." (MAA Reviews, December 10, 2008) "For the applied researcher who does much of her or his own data analysis, this book is a must-have.

John Wiley & Sons Inc Parameter Estimation
Book SynopsisParameter Estimation for Scientists and Engineers discusses estimating parameters of expectation models of statistical observations. It aims to show scientists and engineers, who often are not aware of estimators other than least squares, that statistical parameter estimation has much more to offer than least squares estimation alone.Trade Review“An indispensable tool for scholars and research workers in mathematics and the mathematical sciences.” (Mathematical Reviews, 2009) "Despite its lean size, the book is able to cover many of the techniques and theories in parameter estimation that are core to applied sciences, and so this is certainly a valuable reference for researchers and graduate students alike. The book's exposition is lucid, making it an accessible reading for someone with a reasonable background in elementary statistics. Thus I think anyone in applied sciences and engineering dealing with the implementation of expectation models and aiming to estimate model parameters will find this book helpful. This is a great addition to resources in learning or reviewing statistical tools that emphasize taking advantage of valuable information from data and improving the precision of estimation." (Technometrics, November 2008) "I highly recommend this book to practitioners who want to systematically learn and use, new, better techniques for parameter estimation." (Computing Reviews, September 10, 2008) "…appropriate for students in advanced applied statistics courses…even more useful as a supplemental resource…" (CHOICE, January 2008)Table of ContentsPreface. 1 Introduction. 2 Parametric Models of Observations. 3 Distributions of Observations. 4 Precision and Accuracy. 5 Precise and Accurate Estimation. 6 Numerical Methods for Parameter Estimation. 7 Solutions or Partial Solutions to Problems.
