Four-Parameter Kumaraswamy distribution

Format: Kumaraswamy4(a, b, min, max)


The Four-Parameter Kumaraswamy distribution is a stretched and shifted version of the Kumaraswamy distribution. It is bounded at min and max and can take a wide variety of shapes. It is therefore useful for many of the areas where the Four-Parameter Beta distribution is used. Examples of the Kumaraswamy4 distribution are given below:
