Summary/Abstract: The paper presents the DEA+ method as a tool for estimating the production function and the measure of technical efficiency in data points. A multi-product case is considered. Presentation of the underlying semiparametric frontier model is followed by demonstration of the very algorithm of DEA+ and a discussion of its validity. Finally, the method is illustrated with an empirical example with selected model distributions for each random variable constituting the composed error.
