Then I used the parameter estimates from training data to compute
predicted values for hold-out data (i.e. score the hold-out data).
Aside from MSE or RMSE (Root Mean Square Error), can I use other model
diagnostic metrics to evaluate model fit on hold-out data? For example,
does it make sense to compute AIC value for my model M1 on hold-out data?
