Hi My goal is to do a weighted (by population) factor analysis (of votes) using R. For that I prepared the weigthed cov matrix, which matrix I pass in the factanal function. I'm facing troubles in calculating the scores of a factor analysis using as entry a cov matrix as Factanal is not able to get the scores (normal in the case of absence of any x). I'm looking for a method to calculate the scores "manually" afterward. Does anybody has the way I can retrieve that?
