I came across a problem using Mplus 4 and I am wondering whether some expert could give me some inputs. The problem occurs when I am running multiple group SEM on a dataset with quite a number of missing values. I do use the MISSING = command in the VARIABLE section. But the results tell that Mplus only processed analyses based on full information group pairs--it did not use the information which is available for only one group.

Mplus 5 seems to be able to handle this problem. But does that mean I should buy a new version?

Thanks a lot in advance!

I know of no changes related to missing values between Version 4 and 5 other than that the default in Version 4 was listwise deletion and in Version 5 it is TYPE=MISSING.

I recommend always using the most recent version of Mplus as it is constantly being improved.

Thank you so much for the reply. I added a new line of command in the ANALYSIS section and it works now.

I will think about ordering a new version of Mplus...

Oops, the new line of command is exactly TYPE=MISSING;.
