Detecting Influential Observations in Generalized DEA Model

This paper deals with the problem of detecting influential problems in generalized DEA model. The technique we present here is intended to give a comprehensive description about the measurement of the influence of an extreme efficient DMU on the efficiency of inefficient DMU from several aspects. Since the generalize DEA model contains all kinds of returns-to-scale (RTS) from constant RTS to increasing RTS to decreasing RTS. All of these are discussed under the input-oriented model and the output-oriented model
