Dear All:

I am now struggling with my MSc dissertation and there are two problems with Factor Analysis now. The first one is how can I include non-metric variables into FA, like Gender, Marital status, occupation, residential area,etc? The other one is every time I tried KMO and Barlett's test , the output never show up. there is an notification under the correlation matrix: "the matrix is not positive definite" I don't know what's the meaning for that. And How can I solve these two problems? Or anyone can kindly see my output result, I will send it to you.

Many Thanks

Christina
