PsiLaplace (loc, β,...)

PsiLaplace (β) is an unbounded, fat-tailed distribution that describes the difference between two independent exponentials.  If a random variable X has a Laplace distribution, then |X| has an Exponential distribution.

Enter a scale value greater than 0 for the first argument, loc.  This value determines the scale or range of the distribution. 

Alternate Formulation:  PsiLaplaceAlt

PsiLaplaceAlt is the PsiLaplace distribution defined through alternative arguments.  Two parameters are required and both must be chosen from the following list:  two different percentiles or the standard deviation.
