摘要: One of the tools in theoretical and empirical work on measurement productive efficiency is socalled Free Disposal Hull (FDH) method. As a result its very generous character, many observations belonging to an evaluated dataset are labeled efficient by this Modified FDH, similar spirit as Andersen Petersen's modified Data Envelopment Analysis, may thus be used discriminate between FDH-efficient units. We aim show why particularly for FDH method seems quite apt called valuable complementary tool standard analysis.
