Dear Stata users.
I have a question, maybe more related to the theory so please tell me if I am off-topic.
I was just wondering: what does it change if I remove the intercept that I have in each class-membership function in a latent profile analysis? And most important, when do you suggest to remove it (or constraing the intercepts to be equal across classes?).
Finally, what is the Stata command that allows me to do this? Thank you
