I am planning to purchase spss for my PhD research work. I would like inquire regarding which version of spss will be most suitable for the following statistical analysis: Regression, linear/ non- linear modeling, cluster analysis, principle component analysis, exploratory factor analysis, confirmatory factor analysis, reliability and validity tests, neural network.

You can either purchase the classic, code based edition of IBM SPSS Statistics or the Subscription release with some add on modules you would need for all those analysis.

On below page you will get some information about the different packages .

Scroll down the page and you will see what procedures are included in which add on module for Subscription. The list for Subscription release is on Subscription features section and for the classic, code based edition the list is on Perpetual/term licenses section
