Hi; I am runing runing linear model with four levels. I have not been able to find out what the meaning and usefulness of the variable being reported right after the constant (cons) from the stata output. They are "lns1_1_1:_cons" to "atr3_1_1_2:_cons" . I can imagine they are the changes of the "cons" variable for every level. Nontheless, I see 5 of them, so that is difficult to interpret.

Thanks a lot for your help. Leonardo
