wblskekur

Skewness, kurtosis and kurtosis excess of the Weibull distribution.

This m-file returns the kewness, kurtosis and kurtosis excess of the Weibull distribution with scale (A>0) and shape (B>0) parameters. S, K and E are the size of the output argument.
Weibull distribution is a mainly used for reliability or survival data. Its complementary cumulative distribution function is a stretched exponential function.
Syntax: function [s,k,e] = wblskekur(a,b)

Inputs:
