Prev: Macro Program to mimic "lines"

Hi there,

I'd like to run a factor analysis in SAS. I have a questionnaire (28
questions) filled out by ~400 people. The answers range from 1-10, but
almost all of the answers are positively skewed. I've tried to transform
the data (log, square root, reciprocal) but the data still ends up skewed in
some way. I've heard that tobit factor analysis is a way to deal with
positively skewed data. I was wondering if anyone had some suggestions as
to how they would go about performing an analysis on such data, and if there
are any packages/macros in SAS that might help achieve this?

Thanks for your help.

Best wishes,

Kim
