PsiPareto Distribution

PsiPareto (θ,a,...)

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

Alternate Formulation:  PsiParetoAlt

PsiParetoAlt is the PsiPareto distribution defined through alternative arguments.  Two parameters are required which must be chosen from the following:  2 different percentiles, shape or scale.
