Hi all,

I have a question. Namely, running exploratory factor analysis (EFA) in spss,
it gives explained variance proportion for each eiganvalue. Besides, the
variables that have loading less than .30 can be dropped out from data set
according to this analysis. Herein, reporting the total explained variance in
articles, is it necessary or appropriate to repeat the EFA with reduced data
set and report the total explained variance obtained from second analysis?
thanks in advance
