Hi guys
my apologies for being a newbie to SPSS. But I was wondering, my version does not appear to have probit as an option under the regression analysis. Unfortunately it is a requirement of a project I am working on.  Is this because of my version or am I doing something wrong? Here's what my license Wizard says:

License information for IBM SPSS Statistics installed in C:\Program Files\IBM\SPSS Statistics

Thank you kindly

Hi @Gerald Trinh,

Yes, this is the case.  The PROBIT analysis procedure is part of the IBM SPSS Statistics Regression module.  This module is a part of the IBM SPSS Statistics Standard Edition.  From the licensing information you supplied, it looks like your Graduate Pack is the IBM SPSS Statistics Base Edition.

You can check the available modules by opening a command syntax window within the product ("File -> New -> Syntax") and issue this command:
SHOW LICENSE.

You would see "IBM SPSS Regression" in the resulting table, if PROBIT were available with your current licensing.

In the list of features you supplied, you would have seen:
Feature 1202 - IBM SPSS Regression:
Local license for version 28.0 - GradPak

Probit models are used in regression analysis. A probit model (also called probit regression),
is a way to perform regression for binary outcome variables. Binary outcome variables are dependent variables with two possibilities,
like yes/no, positive test result/negative test result or single/not single.
