The text follows a single model that begins with an experiment consisting of a procedure and observations.* The mathematics of discrete random variables appears separately from the mathematics of continuous random variables.* Stochastic processes are introduced in Chapter 6, immediately after the presentation of discrete and continuous random variables. Subsequent material, including central limit theorem approximations, laws of large numbers, and statistical inference, then use examples that reinforce stochastic process concepts.* An abundance of exercises are provided that help students learn how to put the theory to use.
