Sequential Analysis by Wald Abraham (33 results)

Paperback. Condition: Good. 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.…

Abraham Wald pioneered the science of decision analysis and, in particular, that of sequential decision making. Before Wald, the traditional style of statistical decision was to posit a hypothesis, make a predetermined number of measurements, then make a decision whether to accept or reject the hypothesis. Wald realized that this procedure is quite wasteful, and that many measurements could be saved if given the option to decide at every step whether to continue or stop the measurement process. This idea revolutionized the art of statistical testing and was later developed in the hands of computer scientists into a field known as on-line algorithms. "Most, although not all, of [Wald's] results were summed up in Sequential Analysis (1974). With minor exceptions, the entire contents of this book were obtained by him. Such a phenomenon is rare in mathematical books and indicates the extent to which he founded and dominated the field of sequential analysis" (DSB). Octavo. xii, 212 pp. Sixteen figures, seven tables. Original navy cloth. A very good copy. First edition.…

First edition of a revolutionary work in mathematics and decision theory. Uncommon in the dust jacket. Abraham Wald (1902-1950), a pioneer in the field of operations research, earned his PhD in mathematics at the University of Virginia. He emigrated to the US after the annexation of Austria and worked in econometrics, joining the Columbia faculty in 1941. Wald studied wartime statistics problems as a member of the Statistical Research Group, making the now-famous, counterintuitive determination that it was the damaged parts of military aircraft which returned safely that did not need extra shielding. Wald is considered the founder of the field of sequential analysis, in which sample sizes in statistical analysis are not pre-determined, but data is analyzed as it is collected, lowering the time and financial costs of research. He focused on sequential analysis as a tool for industrial quality control, but it has found uses in many other fields, most notably pharmaceutical clinical trials. First edition; 8vo; diagrams within the text, note in blue ink on front free endpaper, contents faintly toned in the margins; original blue cloth, titles to spine and upper board gilt, minor horizontal production flaw to the cloth, lightly rubbed along the edges, a very good copy in the rubbed and partially toned jacket with a few small chips; 212pp.…
