estfun.AllModelClass() for QMCEM #210

Closed tzoltak closed 2 years ago

tzoltak commented 2 years ago

Hi! I wanted to use Vuong's test implemented in the nonnest2 package to compare two mirt models. Unluckily these models include up to 10 factors and because of this I estimated them using QMCEM. This however makes it impossible to use Vuong test as its implementation relies on calling estfun.AllModelClass() from mirt and it supports only models estimated with EM or BL. Would it be possible to implement estfun.AllModelClass() also for models estimated with QMCEM or MCEM?

It would take a substantial amount of work to do this, but it likely isn't impossible given the current code base. I'll add it to the long-term TODO list, but I'll close this as an issue for now. Thanks for the suggestion.
