Description:	In this paper we measure technical efficiency for each of Embrapa (Brazilian Agricultural Research Corporation) research centers. We model DEA efficiency as a function of contextual variables: revenue generation capacity, partnership intensity, improvement of administrative processes, and impact of technologies generated by the research centers. Production is modeled with random and inefficient errors, in a manner similar to stochastic frontiers. The assessment of significance for the set of contextual variables is carried out by means of linear programming and goodness of fit tests and has a nonparametric basis. We conclude that there is joint significance of all contextual variables.
