PsiLogLogistic Distribution

PsiLogLogistic (γ,β,a,...)

PsiLogLogistic (γ,β,α) is a distribution with a finite lower bound.  The natural log of PsiLogLogistic is a Logistic random variable.  The Log-Logistic distribution can be used to model the time to perform a job or task.

Alternate Formulation:  PsiLogLogisticAlt

PsiLogLogisticAlt is the PsiLogLogistic distribution defined through alternative arguments.  Three parameters are required and all must be chosen from the following list: 3 different parameters, loc, scale or shape.
