The Weibull distribution is a continuous probability distribution that is used to model the lifetime of a component or system. The Weibull distribution is often used in reliability engineering to model the failure time of a component or system.
The Weibull distribution has two parameters, the shape parameter and the scale parameter. The shape parameter determines the shape of the distribution, and the scale parameter determines the scale of the distribution.
The Weibull distribution is named after Swedish mathematician Waloddi Weibull, who first described the distribution in 1939.
