The expository material is a shelf of volumes or books,
each dedicated to a fundamental topic. Each volume is divided into chapters,
similar to chapters in a conventional book, and each chapter is in turn divided
into web pages, similar to sections in a conventional book.

The books explore the basic theory and applications of
distributions, probability, mathematical statistics, and certain special models
and stochastic processes.
The expository text assumes knowledge of calculus, at the standard
undergraduate level. A few sections require knowledge of linear algebra,
at the standard undergraduate level. No prior knowledge of probability or
statistics is assumed.

A series of exercises guides the student through the
development of both the mathematical theory and probabilistic intuition.
