In 1943, while in charge of Columbia University's Statistical Research Group, Abraham Wald devised Sequential Design, an innovative statistical inference system. Because the decision to terminate an experiment is not predetermined, sequential analysis can arrive at a decision much sooner and with substantially fewer observations than equally reliable test procedures based on a predetermined number of observations. The system's immense value was immediately recognized, and its use was restricted to wartime research and procedures. In 1945, it was released to the public and has since revolutionized many aspects of statistical practice. This book is Professor Wald's own description of the system. Part I contains a discussion of the general theory of the sequential probability ratio test, with comparisons to traditional statistical inference systems. Part II discusses applications that illustrate the general theory and raise points of theoretical interest specific to these applications. Part III outlines a possible approach to the problem of sequential multi-valued decisions and estimation. All three sections can be understood by readers with only a background in college algebra and a first course in calculus. Mathematical derivations of somewhat intricate nature appear in the appendix. Sequential Analysis offers statistical researchers a time- and money-saving approach, introduces students to one of the major systems in contemporary use, and presents those already acquainted with the system with valuable background information.

This guidebook is intended to assist students, housestaff, and practitioners in clinical situations. Initial sections review EKG interpretation and a sequential analysis of the EKG. Subsequent sections enable the reader to build a differential diagnosis based on EKG abnormalities. Final sections provide diagnostic criteria to narrow the list of possibilities and to arrive at a specific diagnosis.

WALD, Abraham was born in 1902 in Cluj, Romania.
Mathematical statistician whose work on decision theory and sequential analysis is of outstanding importance. He also did original work in econometrics and mathematical economics, including existence proofs for general equilibrium, seasonal corrections of time series, formulae for index numbers, the Cournot duopoly problem, and stochastic difference equations.
