Stochastic processes are necessary ingredients for building models of a wide variety of phenomena exhibiting time varying randomness. This text offers easy access to this fundamental topic for many students of applied sciences at many levels. It includes examples, exercises, applications, and computational procedures. It is uniquely useful for beginners and non-beginners in the field. No knowledge of measure theory is presumed.Resnick, Sidney is the author of 'Adventures in Stochastic Processes', published 1992 under ISBN 9780817635916 and ISBN 0817635912.
