Dear Statalists

I am doing an exploratory factor analysis of continous and dichotomous variables. Is it fine do do a seperate analysis on the two sets factor analysis for continous variables and polychronic analysis for dichotomous variables or there is a way to analyse both together.

Kind regards

Jonathan

The user-written polychoric accepts both continuous and ordered-categorical variables at once, and yields the proper correlation coefficient between pairs. You can feed the returned matrix from it to the official Stata command factormat.

search polychoric

for where to install it from.

Dear Joseph
Than you very much. I have done so and got satisfactory results.
