Hi Everyone, I am facing the problem of running the latent class model in R. By "mmlcr", the program always shows as following,
Error in model.frame(formula, rownames, variables, varnames, extras, extranames, : invalid variable type Does anyone happen to know why this happened? I am stopped at this step. Thank you very much for the answer.
