The most important random variables and random processes are developed in systematic fashion using model-building arguments.


For example, a systematic development of concepts can be traced across every chapter from the initial discussions on coin tossing and Bernoulli trials, through the Gaussian random variable, central limit theorem, and confidence intervals in the middle chapters, and on to the Wiener process and the analysis of simulation data at the end of the book.

The goal is to teach the student not only the fundamental concepts and methods of probability, but to also develop an awareness of the key models and their interrelationships. The development of an intuition for randomness can be aided by the presentation and analysis of random data.

Where applicable, important concepts are motivated and reinforced using empirical data. Every chapter introduces one or more numerical or simulation techniques that enable the student to apply and validate the concepts. Topics covered include: Generation of random numbers, random variables, and random vectors; linear transformations and application of FFT; application of statistical tests; simulation of random processes, Markov chains, and queueing models; statistical signal processing; and analysis of simulation data.

The sections on computer methods are optional. However, we have found that computer generated data is very effective in motivating each new topic and that the computer methods can be incorporated into existing lectures. We opted to use Octave in the examples because it is sufficient to perform our exercises and it is free and readily available on the Web.

This edition includes a new chapter that covers all the main topics in an introduction to statistics: Sampling distributions, parameter estimation, maximum likelihood estimation, confidence intervals, hypothesis testing, Bayesian decision methods and goodness of fit tests.

The text includes problems, nearly double the number in the previous edition. Problems are identified by section to help the instructor select homework problems.

Additional problems requiring cumulative knowledge are provided at the end of each chapter. Answers to selected problems are included in the book website. A Student Solutions Manual accompanies this text to develop problem-solving skills. An Instructor Solutions Manual with complete solutions is also available on the book website. Care is taken in the first seven chapters to lay the proper groundwork for this transition.

Thus sequences of dependent experiments are discussed in Chapter 2 as a preview of Markov chains. In Chapter 6, emphasis is placed on how a joint distribution generates a consistent family of marginal distributions. Chapter 7 introduces sequences of independent identically distributed iid random variables. Chapter 8 uses the sum of an iid sequence to develop important examples of random processes.

The traditional introductory course in random processes has focused on applications from linear systems and random signal analysis. However, many courses now also include an introduction to Markov chains and some examples from queueing theory. We provide sufficient material in both topic areas to give the instructor leeway in striking a balance between these two areas. Here we continue our systematic development of related concepts.

Thus, the development of random signal analysis includes a discussion of the sampling theorem which is used to relate discrete-time signal processing to continuous-time signal processing.

In a similar vein, the embedded chain formulation of continuous-time Markov chains is emphasized and later used to develop simulation models for continuous-time queueing systems. In addition to the standard topics taught in introductory courses on probability, random variables, statistics and random processes, the book includes sections on modeling, computer simulation, reliability, estimation and entropy, as well as chapters that provide introductions to Markov chains and queueing theory.

The flow chart below shows the basic chapter dependencies, and the table of contents provides a detailed description of the sections in each chapter. The first five chapters without the starred or optional sections form the basis for a one-semester undergraduate introduction to probability. A course on probability and statistics would proceed from Chapter 5 to the first three sections of Chapter 7 and then xii Preface 1. Probability Models 2.

Basic Concepts 3. Discrete Random Variables 4.

Continuous Random Variables 5. Pairs of Random Variables 6. Vector Random Variables 7. Sums of Random Variables 8. Statistics 1. Review Chapters 2. Sums of Random Variables 7. Random Processes Markov Chains Queueing Theory to Chapter 8. A first course on probability with a brief introduction to random processes would go from Chapter 5 to Sections 6. Many other syllabi are possible using the various optional sections.

A first-level graduate course in random processes would begin with a quick review of the axioms of probability and the notion of a random variable, including the starred sections on event classes 2.

The material in Chapter 6 on vector random variables, their joint distributions, and their transformations would be covered next. The discussion in Chapter 7 would include the central limit theorem and convergence concepts. The course would then cover Chapters 9, 10, and Proof of the central limit theorem.

Chapter 1 addresses this challenge by discussing the role of probability models in engineering design. Case 1: You can check your reasoning as you tackle a problem using our interactive solutions viewer. The expected value of random variables.

A mathematical model consists of a set of assumptions about how a system or physical process works. Mean square derivatives. Optimum linear systems. Closed networks of queues.
