Weibull Random Number Generator
The Weibull distribution with parameters α and β is often used in predicting time to failure and other processes in physics, engineering, and materials science. When you set α = 1, you obtain the exponential distribution; when you set α = 2, you get the Rayleigh distribution, which arises when studying two-dimensional wind speed vectors.
You can generate random variables from a Weibull distribution using the calculator below.
The Weibull probability density function is
PDF(x) = αβ-αxα-1e-(x/β)α x ∈ [0, ∞)
The mean, median, mode, variance, and skewness of the Weibull distribution are somewhat complicated functions of α and β:
