Discrete Weibull distribution
In probability theory and statistics, the discrete Weibull distribution is the discrete variant of the Weibull distribution. Introduced by Toshio Nakagawa and Shunji Osaki in 1975, it is a discrete analog of the continuous Weibull distribution. It models primarily random variables concerning time to failure or time between events, particularly when that time is measured in discrete units. The discrete Weibull distribution is infinitely divisible only for .
