I am running a CFA model dealing with categorical variables in MPLUS. In the output, the message says "Categorical variable XX contains less than 2 categories."
I check into the data. I found in this categorical variable: there ARE exactly 2 categories (0/1), but just 2 observations among all have the value 1. Is the error in the output because of this reason?
Please send the input, data, and output to firstname.lastname@example.org. This would not be the problem. You most likely have blanks in the data set which are not allowed with free format.

Thank you, professor Muthen. Yes, this is not a problem. I just found the true problem: I did not type the variable names handily; I just pasted the variables names from wordpad (because there are a lot of them); it seems that the spaces between variable names in wordpad are different from that in Mplus; Unless you redo the spaces between names in Mplus, you may get this or that problem in the running process, which may prove not to be the true problem of the modeling.
