Incorporating the effect of the exogenous variables into the estimation of efficiency measures is one of the issues that have received more attention in recent years within the operations research literature. The aim of this work is to assess the performance of two recently developed methodologies such as the nonparametric conditional model and the StoNEZD (Stochastic Nonparametric Envelopment on Z-variables Data) method, which combines both parametric and nonparametric techniques. To do this, we conduct a Monte Carlo experiment with various alternatives production functions. According to the results, StoNEZD methodology performs better, although the conditional DEA model also provides acceptable results in all the proposed scenarios, thus it can be considered as a valid alternative when the available data cannot be adapted to the specific framework of the StoNEZD model.
