Hi everyone,
I am really new in OpenMx. I am trying to do a bivariate analysis (dicotomic-quantitative) and I have some questions.
1-I would like to know if I should do a univariate analysis previously I mean in the bivariate analysis The best fitting model could be AE for example, for two variables but in the univariate I could have AE model for one variable and ACE model for the other variable.
2-There is a big difference in the means of one variable and I have problems in the saturated model. I think I should try a sex limitation model, but I cannot find a bivariate sex limitation script.
3- In the sense of that I have read a bivariate sex-limitation model is quite difficult and I would like to know when I have to do cholesky decomposition and how. I am quite confused with that.
PD: I use Boulder´s scripts
Thanks in advance any help or material will help me.
Best regards
