Notice you hijacked the thread titled "Tips on Posting questions to the SPSS list."....
Please begin a new topic after deleting this unrelated question from the thread!

"AND!!!!
DMM1.  Don't hijack previous threads with an OT/different topic.  There is a NEW THREAD option and replying to a "how do I mutilate my data using the SPSS ginzu option" with a "My table isn't coming out right" or "Python sucks/Macros rule" is bound to bury your question in the bowels of something completely irrelevant to your cause and the right people won't see it.  Personally I use Nabble to view this group and Changed subject lines end up threaded under the original topic. "

I suspect your question is rather general and tangential to SPSS.  PCA vs PAF vs SEM?
I'll bet if you Google these terms you will find more than enough to keep you busy for months.

This is Bilal Khalid. I am doing research work in the field of Construction Engineering and Management. The Statistical analyses techniques which I am using are confirmatory factor analysis (CFA) along with structure equation Modelling (SEM). Initially I started with PCA to shrink my factor List (I had 3 Principle categories in which 26 sub categories are there along with 106 variables/statements in sub categories). Finally i have 9 factors in which 29 variables/statements are there. Now, Project my supervisor suggests me to go with Principle Axis factoring technique because he is not satisfied with the final outputs of PCA. My 1st question is, should i go with PAF again to validate my factor results? if yes then kindly mention here some link which can help me in understanding the basics of PAF and also the threshold values of outputs of PAF.
