Do you have any idea how I can get the cumulative distribution function (CDF) for inverse-normal (Gauusian) distribution? Modeler 18.2 doesn't have that specific function, and I need it to calculate a Vasicek test.

$\begingroup$ I would be astounded to find any statistical package that does not include this function: consult the SPSS documentation. The top Google hit for "SPSS inverse normal distribution" takes you there: ibm.com/support/knowledgecenter/en/SSLVMB_24.0.0/spss/base/…. $\endgroup$– whuber ♦Commented Aug 9, 2019 at 12:28

$\begingroup$ I need it for SPSS Modeler - the data mining client from the SPSS family. $\endgroup$– JulianCommented Aug 9, 2019 at 13:00

$\begingroup$ You might, then, want to focus on its specific documentation. Given the name "SPSS" I had supposed it would share functionality with SPSS, but I could be wrong. $\endgroup$– whuber ♦Commented Aug 9, 2019 at 13:02

$\begingroup$ And so I have, and it does not exist in there, therefor, I am asking the community here. :) $\endgroup$– JulianCommented Aug 9, 2019 at 13:32

$\begingroup$ Unless someone kindly offers a suggestion in a comment--which sometimes happens--you're going to be better off asking an SPSS-specific community. There should be links to such communities available through the hyperlinks in the off-topic message above. $\endgroup$– whuber ♦Commented Aug 9, 2019 at 14:30
