@littlehifive could you share more information so we can reporduce the error? Something like sample size, variable means, covariance matrix, and full code? With this we could simulate similar data...

@littlehifive Thnsk, I see what the problem is. I think this change is related to the logl change that @ecmerkle mentioned earlier. I think that change affected the pD calculation...

Giving the exaplanation about the original data, I find it interesting that this seems to be a good diagnostic of the data mismatching the models likelihood, and that loo and...

I am not sure how common it is, but have seen different authors mentioned it as an option of the identification constraints that can help with label switching. In these...

I find Mplus "language" cumbersome. I think LatentGold is more clear about this, see page 62 of the syntax guide https://www.statisticalinnovations.com/wp-content/uploads/LGSyntaxusersguide.pdf Where we have the model parameters varied across groups,...

Here is a thread of the OpenMx forum on how to add predictors in a growth mixture model, this could be useful to extend for the multiple group example https://openmx.ssri.psu.edu/node/4428

I think a possible solution is to fix the `$values` slot of the `S` model matrix for the exogeneours variables to the observed variance in the data. Because right now...

I think this makes sense, and matches how lavaan handles is in several parts. For example, I get the same estimates, number of parameters, df. But the logLik is different....

We would need to adjust the fit measures in OpenMx to ignore the x side. Which I dont think we can, or would be easy. I would suggest to add...

Is there an update on the progress of this fix? Our research team has found the same issue
