]
represents a Weibull distribution with shape parameter

and scale parameter

The probability density for value x in a Weibull distribution is proportional to for , and is zero for . »

WeibullDistribution can be used with such functions as Mean, CDF and RandomReal. »

The mean and variance of a Weibull distribution depend on the Gamma function:
