PsiTheoStdDev(cell_or_name)

Returns the standard deviation of the specified distribution.    

Example:  If A1 =PsiNormal(0,1) then

=PsiTheoStdDev(A1) returns the standard deviation of the PsiNormal(0,1) distribution.

Note:  Analytic Solver statistics functions that begin with PsiTheo return a statistic on a simulation input distribution.
