Hi Walter, If you do not see optimal scaling and correspondence analysis below the menu Analyze - Dimension reduction, then your license does not include the Categories option add on module .
You can open a new syntax window with file - new - syntax and run below command:
SHOW LICENSE.
If the resulting table on output does not include the Categories add on, then you need to purchase it from your verndor or from IBM. Maybe your University have a code for the add on for you.
