-====== Beta-PERT Distribution ======
+====== Beta (Generalized) Distribution ======
-Specifies a beta-PERT distribution with scale a and b (min/max), shape c (most likely) and scale labmda.
+Beta (Generalized) Distribution
+In probability theory and statistics, the Beta distribution is a family of continuous probability distributions defined on the interval [0,1] parameterized by two non-negative shape parameters, typically denoted by alpha and beta.
+This is a generalized version of the Beta distribution with dynamic interval defined by parameters min and max.
+f(x,alpha,beta,min,max) =  //(((x-min)/(max-min))^(alpha-1)*(1-((x-min)/(max-min))^(beta-1)/Beta(alpha,beta)-min)/(max-min)//
+where
+Beta(alpha,beta) = ..integral from 0 to 1 of t^(z-1)*(1-t)^(w-1) dt.
+support [min <= x <= max]
