Every couple of years, I mention OpenMx on this list:


I don't know exactly how much of Mplus's functionality it provides, but suspect it would be close to 100%.

As to the OP's question, we don't know how much data is actually missing, or what pattern that takes. We also don't know why some of the fitted models differ by 0 d.f.  If we did impute the data 5 times, wouldn't that give us an 80 h run-time?

Cheers, David.
