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

From the Syntax Reference Guide under MATRIX...
IDF.NORMAL. IDF.NORMAL(prob, mean, stddev). Numeric. Returns the value from the normal distribution, 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 here On Sat, Dec 1, 2018 at 1:19 PM Beckstead, Jason < [hidden email]> wrote:

Thanks Jon. Indeed, I was not seeing that in a PDF of the CSR manual for
SPSS 25.0.0.0; nor is it showing up in the online (html) version of the CSR
manual here:
https://www.ibm.com/support/knowledgecenter/en/SSLVMB_25.0.0/statistics_reference_project_ddita/spss/base/syn_matrix_matrix_functions.htmlBut if I open the CSR manual for SPSS 25.0.0.2 via the menu (Help > CSR), I
do see that info. Here is the full path to finding it, for those who may be
interested.

I have reported this to the Pubs folks. They have been pretty good about promptly fixing problems in the online doc. As Bruce says, the installed 25.0.0.2 CSR does document these functions, but the Command History section for MATRIX was missed. Thanks Jon.

Correction: although the CSR installed with fixpack2 for 25 documents the new CDF and IDF functions, they are not actually in 25.0.0.2. Currently they are only in Subscription. Presumably they will eventually show up in the nonSubscription version. I have reported this to the Pubs folks. They have been pretty good about promptly fixing problems in the online doc. As Bruce says, the installed 25.0.0.2 CSR does document these functions, but the Command History section for MATRIX was missed.
