Dear Statalisters,
I�m facing a problem while trying to perform Factor Analysis. Hope someone can help me.
I have a dataset of food acquisition data (indicating the average per capita acquisition of some food groups) where the unit of analysis are clusters of household (basically it is an aggregated dataset of household food acquisition data). The original dataset contain a �probability weight variable� (PW) which has been used for all the analysis so far. The problem is that I can not use the �pw� to perform Factor Analysis (starting with fac command).
Should I just not weight the data while performing factor analysis?
Another option would be to create other weight variable, pointing the number of households contained in each cluster, and use the analytical weighting (aw). Would this be more desirable than use no weight at all?
I use stata 9.2
Sorry about re-sending this message, but I noted some misspelling on my last post (with the same doubt) and felt like I should do it again.
Thank you very much.
Best
Rafaelcla
