Subject: Re: Reference for factor loading cut-off
Two questions: why principal components and why a varimax rotation? As far as cut-offs go, why not test them. Some people use 1/sqrt(N-3) as an estimate of the standard error. There are programs that do significance tests of loadings for EFAs, like Mplus.

Subject: Reference for factor loading cut-off
I am working PCA using varimax rotation. The editor of a journal suggested a cut-off of 0.5 on the rotated factor loadings. Using that cut-off is the same as throwing my paper into the garbage can since only few variables would qualify such criterion. I am looking for a reference about the cut-offs. I appreciate your help.
