Dear Muthen,

I want to run a twolevel analysis without predictors on level 1 or 2, just considering the nested structure of the data. The objective is to get the correlation coefficients of 2 dependent variables (CFT-SUM and MC_SUM), the intraclass correlation and the estimated sample statistics for "within" and "between". This is my syntax:

data: file = cftmc.dat;

variable: NAMES = CFT_SUM klasse MC_Sum;
MISSING = all(-99);


CLUSTER = klasse;

Analysis: TYPE = TWOLEVEL;

Model: %WITHIN%


output: sampstat;

My fit indices are bad (RMSEA .404, CFI .004, TFL .004), is this due to a syntax error? I get the warnings: "variable is uncorrelated with all other variables CFT-SUM" and "variable is uncorrelated with all other variables MC-SUM". As I have no predictors an level 1 and 2, this is what I intended, isn't it?

Thank you for your help!

The variables are probably correlated in the data so use WITH on both levels.

Thanks a lot for pointing that out!
