Syntax

Weibull.density(u, u_min=0, u_max=1, lambda=1, k=1);

Description

This function computes the probability density function according to a truncated Weibull distribution with minimum value u_min, maximum value u_max, scale parameter of original distribution lambda and shape parameter of original distribution k. Plot of the function:

Example

density(0.5)             // = 0.9595173756674719
density(0.5,0,0.8,0.5,2) // = 1.5948036466479143
