PsiTheoKurtosis (cell_or_name)
Returns the analytic kurtosis (4th moment) value for the specified distribution.
Example: If A1 =PsiNormal(0,1) then
=PsiTheoKurtosis(A1) returns the kurtosis of the PsiNormal(0,1) function.
Note: Analytic Solver statistics functions that begin with PsiTheo return a statistic on a simulation input distribution.
