PsiPareto2 Distribution

PsiPareto2 (b,q,...)

PsiPareto2 is an alternate form of the Pareto distribution with a finite lower bound of 0, and a shape parameter q.  Like PsiPareto (θ,a), it can be used to describe or model wealth distribution, sizes of particles, etc.  It is the exponential of an Exponential random variable.

Alternate Formulation:  PsiPareto2Alt

PsiPareto2Alt is the PsiPareto2 distribution defined through alternative arguments.  Two parameters are required and both must be chosen from the following list:  2 different percentiles, scale or shape.
