Hi All,
I may have this question in the wrong area, but here goes - I'm trying to run a basic, level 1 model with data at 4 time points. The model runs without error messages, but the output appears to be based on exactly half of my data (N=683) rather than the entire sample in my data file (N=1366).

Based on the resolution to an old thread on this board, I checked the syntax for the Data Is, and it is fine. I've double-checked the dataset, and it's all there.

Has anyone ever had this happen? I appreciate any and all suggestions!

This could happen ff you have more variable names than columns in your data set or if you have blanks in the data set and are reading it free format. If you can't see the reason, send the output, data, and your license number to

Dr. Muthen, Thanks for the response. The solution - the *.inp with my data was 160 characters wide. Thanks!

I encountered the same question. Can someone help me out?

You must have more variable names that you have columns in the data causing two records to be needed for each observation.
