Hi,

I ran factor analysis using R and SAS. However, I had different outputs from
R and SAS.
Why they provide different outputs? Especially, the factor loadings are
different.
I did real dataset(n=264), however, I had an extremely different from R and
SAS.
Why this things happened? Which software is correct on?

factanal uses ML-method for estimating the loadings. SAS and SPSS use
the principal component method. Maybe you should better use princomp +
varimax. However, the rotated solutions are basically the same :)

Yours sincerely

Sigbert
