Description
Book SynopsisAiming to contribute to reliable and realistic predictions, this book focuses on sampling times from a few seconds to a few hours. Its objectives include: developing definitions of statistical terms; identifying areas where further information is required to define concentration variability statistics; formulating an operation model; and more.
