Hello:

After having run a CFA model using two different versions of Mplus (4.2/6) I wanted to ask if it is possible that in the earlier version the model won't converge but in the later it does just fine. Nothing about the models changes between runs, but I am wondering what may be the reason for the non-convergence/convergence (ML estimation).

There are so many minor changes that have happened between 4.2 and 6, it is difficult to say. It could have to do with better starting values or small algorithmic changes. There have also been compiler changes. Any one of these could be the reason.

This was indeed my thinking, I just wanted to be sure. Thank you.
