GSEM in your Stata does not support ordinal dependent variables directly

[kresna mansueto]

Is this possible for Stata 18 SE: GSEM in your Stata does not support ordinal dependent variables directly. ?

[Jeff Pitblado (StataCorp)]

Where are you seeing this?

Stata's gsem command can fit ordinal outcome models. It can fit this outcome model for cross-sectional data, multi-level data, or with latent classes.

Here is an example where gsem fits a multi-level ordinal logistic model, using an example from the manual entry [ME] meologit.

. 
. gsem thk <- prethk cc##tv I[school], family(ordinal) link(logit)

Fitting fixed-effects model:

Iteration 0:  Log likelihood =  -2212.775  
Iteration 1:  Log likelihood =  -2125.509  
Iteration 2:  Log likelihood = -2125.1034  
Iteration 3:  Log likelihood = -2125.1032  

Refining starting values:

Grid node 0:  Log likelihood = -2136.2426

Fitting full model:

Iteration 0:  Log likelihood = -2136.2426  (not concave)
Iteration 1:  Log likelihood = -2120.2577  
Iteration 2:  Log likelihood = -2119.7574  
Iteration 3:  Log likelihood = -2119.7428  
Iteration 4:  Log likelihood = -2119.7428  

Generalized structural equation model                    Number of obs = 1,600
Response: thk    
Family:   Ordinal
Link:     Logit  
Log likelihood = -2119.7428
