Opis

A comprehensive perspective on Weibull models

The literature on Weibull models is vast, disjointed, and scattered across many different journals. Weibull Models is a comprehensive guide that integrates all the different facets of Weibull models in a single volume.

This book will be of great help to practitioners in reliability and other disciplines in the context of modeling data sets using Weibull models. For researchers interested in these modeling techniques, exercises at the end of each chapter define potential topics for future research.

Organized into seven distinct parts, Weibull Models: Covers model analysis, parameter estimation, model validation, and applicationServes as both a handbook and a research monograph. As a handbook, it classifies the different models and presents their properties. As a research monograph, it unifies the literature and presents the results in an integrated mannerIntertwines theory and applicationFocuses on model identification prior to model parameter estimationDiscusses the usefulness of the Weibull Probability plot (WPP) in the model selection to model a given data setHighlights the use of Weibull models in reliability theory

Filled with in-depth analysis, Weibull Models pulls together the most relevant information on this topic to give everyone from reliability engineers to applied statisticians involved with reliability and survival analysis a clear look at what Weibull models can offer.

Recenzje

"…valuable to readers seeking an overview of Weibull models and…a valuable contribution to libraries…" ( Journal of the American Statistical Association, September 2005)

“…may serve as a handbook in research and teaching…” (Zentralblatt Math, Vol.1047, No.22, 2004)

"The book is generally well written and easy to read. It could serve as a useful reference to practitioners…and researchers." (Technometrics, November 2004)

"The literature of Weibull models is vast, disjointed, and scattered across many different journals. There are a couple of books devoted solely to the Weibull distribution, but these are oriented toward training and/or consulting purposes. There is no book that deals with the different Weibull models in an integrated manner. This book fills that gap." (Mathematical Reviews, Issue 2004h)
