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.
