Dear Muthen,

Hello, I study in Mplus and then I think my dataset is the similar pattern Ex 9.13. But, now I couldn't figure out the X, W variables.
I got the your answer, even if I just use the outcomes, it is fine. So, I try to change the program comment.

* Question(1)
Like this:-------------------------------------------------------------
TITLE: this is an example of a two-level Growth model for a categorical outcome1
(three-level analysis)
DATA: FILE IS ex9.13.dat;
VARIABLE: NAMES ARE u1-u4 clus;
CATEGORICAL = u1-u4;
CLUSTER = clus;
ANALYSIS: TYPE = TWOLEVEL mixture;
MODEL: %WITHIN%
iw sw | u1@0 u2@1 u3@2 u4@3;
%BETWEEN%
ib sb | u1@0 u2@1 u3@2 u4@3;
OUTPUT: TECH1 TECH8;
-----------------------------------------------------------------------
The Mplus say to me, it can't run it.
I can't hand it. why I get this message?

* Question(2)
I look at the Ex 9.13 dataset.
X and W are contiunous variabels. If X and W are catergoical variabels, it is fine?
And, I need more explain about the X, W variables. Still confuse.

Thank you so much for your helping.

1. You don't have a mixture model so you should delete "mixture" from your TYPE = statement.

2. x and w can be categorical. Why don't you start your modeling without such variables. But you should really read the multilevel/growth literature and/or take a course - which is very clear on the meaning of such variables - before you do analyses of this kind.
