PsiLogNormal Distribution

PsiLogNormal (μ,σ,...)

PsiLogNormal (µ,σ) is a distribution with a finite lower bound and has mean µ and standard deviation σ.  The LogNormal distribution can be used to model quantities that are products of many small independent variables.  The natural log of PsiLogNormal is a Normal random variable.

Alternate Formulation:  PsiLogNormalAlt

PsiLogNormalAlt is the PsiLogNormal distribution defined through alternative arguments.  Two parameters are required and both must be used in the following combinations:  2 different percentiles, percentile and mean or percentile and standard deviation.
