Inverse normal distribution function in MATRIX

 Hi All,   I am working with the MATRIX-ENDMATRIX procedure. I have a square matrix of probabilities and need to transform each value into a z-score. I note that there is a matrix function: CDFNORM referenced in the syntax guide (this takes z-scores and returns probabilities) but I do not see what I would guess I need, something like “IDFNORM”. Any help would be appreciated.   Jason   _____________________________________________________________  Jason W.

Re: Inverse normal distribution function in MATRIX

 From the Syntax Reference Guide under MATRIX...IDF.NORMAL. IDF.NORMAL(prob, mean, stddev). Numeric. Returns the value from the normaldistribution, with specified mean and standard deviation, for which the cumulative probability is prob.The cdf and idf functions mimic the corresponding functions in the regular transformation system.  There is also a PROBIT function that is a special case of IDF.NORMAL.You might have missed this, because there is also a CDFNORMAL function that doesn't follow the pattern.I see this in the 25.0.0.2 SRG.  It is also in the Subscription version, I think, but would not be in 25.0.0.0 or earlier versions.  If you haven't installed fixpack 2, you can find it hereOn Sat, Dec 1, 2018 at 1:19 PM Beckstead, Jason <[hidden email]> wrote: Hi All,   I am working with the MATRIX-ENDMATRIX procedure.
