This calculator computes the parameters m and η, as well as the mean lifetime μ, for the Weibull distribution f(t) = (m/η) * (t/η)^m * exp[-(t/η)^m], which is used to analyze the lifespan of components and other items.Calculations are performed using the same method as the Weibull plot. The median rank is used to calculate the probability of failure. The maximum number of data points is 20.
