Hello!
Has anyone attempted to do a principle component factor analysis on a large
national data set that requires stratified weighting (STRATA) and cluster
weighting (PSU)? In Stata, when these weights are activated, you have to use
commands that start with SVY. However, I noticed that there were no SVY
commands for factor analyses ... any suggestions?
I guess my real question is: can you use these weights and do a factor
analysis, or do you simply run the factor analysis without the weights, run
another test (like a reliability test) on the variables, then create a scale
or index to be used as an independent variable in, say, a regression? Of
course, the regression will have to use weights, but perhaps you don't need to
use stratified and cluster weights in a factor analysis.
Please help!
Thanks, Alison
