Latent class analysis categorical variables

[Pooja Dewan]

Dear all,

I have been using latent class analysis in STATA 15 and have been able to get results using the gsem command for binary variables using the following code:

gsem (isch afib ckd dbt hyp pvd <- _cons), logit lclass(C 3)

However when i try to analyse categorical variables, I get an error message

.gsem (bmigroup  hb_class  age_gp <- _cons), ologit lclass(C 2)

invalid path specification;
ordinal response bmi_fr1 may not have an intercept

Could anyone help me with this?

Thank you
