Compiling findings from many scientific journals and research papers, this handbook focuses on the origin, statistical properties, and related distributions of the Weibull distribution. It also presents various approaches to estimate the parameters of this distribution under all possible situations of sampling data as well as approaches to parameter and goodness-of-fit testing. The author provides illustrative examples from the biological, environmental, health, physical, and social sciences and lists several statistical software packages capable of performing Weibull analysis. The extensive bibliography includes 1,200 research papers on the theory and application of the Weibull distribution.
