Pseudo
The R2 values for the reduced model are identical to those for the original model. This is evidence in favor of the reduced model.

Classification table for reduced model
The classification table somewhat complicates matters. The overall classification rate of 37.0% for the reduced model is comparable to the original model, which is evidence in favor of the reduced model. However, the reduced model shifts the predicted response of 3.8% of the voters
