Dear Friends, I tried to use LCA in stata15 for my paper. I want to classify the observed people into 4 or 5 groups. Then I could analyze the characters of every group But I met some errors in my results, and I don’t know how to solve it. I really need your help.
Thank you very much!

2. when I used the code “gsem (hr hq hw hl hv ha <-,ologit),lclass(C 4)” , why it still printed “not concave”?
3.as the picture
