This paper considers efficiency of a Decision Making Unit (DMU) in Data Envelopment Analysis (DEA) with a generalized additive model and a categorical structure. Specifically, it extends the categorical framework in DEA for controllable and noncontrollable situations, and it gives simple, but powerful, tests to determine whether or not a given DMU is efficient.
