Bilal,
The practical answer is that you should do what your supervisor requests. I understand that faculty-student relationship expectations at your school may be different in some ways than would be true in the US but he's the teacher so he should be able to coherently (and correctly) explain his reasoning, which means you need to have some background. Why haven't you googled 'factor analysis'? Other, smarter, people have written book on factor analysis.

Subject: Re: Tips on Posting questions to the SPSS list.

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.

Regards,
Bilal Khalid
