Hello dear all,
I was trying to understand the output tables especially the first one, mlogit model for C (I have attached the output below). I have searched on Stata documentation on SEM Release 15 and LCA example 50g, but to no avail. Ex 50g ignores those tables and continues with the output result from –estat lcmean- My questions are
  1. what does the p-value for _cons in the first table indicate (in my case they are insignificant)? AIC and BIC values for 3 class solution are smaller than one class solution in my analysis
  2. if the intercept coeficient for an item (x) remains insignificant as in:
    Code:
    bin_ettor_life  //in my third class
    for one class but significant in the other classes, what does this indicate? This is related to the table output of logistic regression models of the third classes
The documentation for LCA is a bit lacking (subjective opinion) in practical examples wrt to other SEM documentations, or it may be that I am novice user.
thank you for your help

Code:
Generalized structural equation model           Number of obs     =      2,669
Log likelihood = -17965.754
