Hello,

 

Can I use AIC or BIC to compare identical models that used FOCE-I for one run and QRPEM for another run? 

 

Can I use AIC or BIC to compare non-nested models?

 

Thanks,

Erik

Erik,

 

I checked with our dev team and they confirmed:
 
it is not feasible to compare the -2LL given by different algorithms (QRPEM and FOCE) due to different methods of LL compuation.
 
However, you can use AIC or BIC to compare non-nested models, provided the same engine with the same options are used.
 
Hope, this helps.
 
Bernd
