I have to run a factor analysis on a dataset made up of dichotomous variables (0=yes, 1= no) and I don´t know if I'm on the right track.
tetrachoric() I create a correlation matrix, on which I run
The result is quite near to the results i receive when using MixFactor, but it´s not the same.
- Is this ok or would you recommend another procedure?
- Why does
factanal()produce an error? (
