DEA (Data Envelopment Analysis) method and its modification are considered in the paper. An inefficient frontier is suggested to be introduced. The intersection of the efficient frontier and inefficient frontier is researched. The intersection of both frontiers helps to construct a hyper plane to separate a sample into two classes.
