i have fit several sets of models with and without training data. in each case, introducing the training data has worsened model fit as measured by BIC. should i conclude from this that the training data is not very accurate (a possibility) or is there a statistical reason for this phenomenon?

The metric of the likelihood changes when training data are introduced, so BIC values are not comparable with and without training data.

I assume the same would hold for two different sets of training data, i.e., the BIC would not be comparable.
