Waloddi Weibull Ernst Hjalmar Waloddi Weibull (18 June 1887 – 12 October 1979) was a Swedish civil engineer, Materials science, materials scientist, and Mathematician#Applied mathematics, applied mathematician. The Weibull distribution is named after him. Edu ...

Weibull distribution In probability theory and statistics, the Weibull distribution is a continuous probability distribution. It models a broad range of random variables, largely in the nature of a time to failure or time between events. Examples are maximum on ...
