Productivity analysis

DEAPack provides four principal productivity families: adjacent-period Malmquist, Luenberger, Malmquist–Luenberger with undesirable outputs, and Hicks–Moorsteen. The package reference also documents common-reference comparisons and specialized research methods so every implemented public method remains discoverable.

The FGNZ constructor is a source-qualified preset of the adjacent-period Malmquist operator; it is not a fifth principal family. Enhanced FGNZ and Ray–Desli are specialized sections of the Malmquist package reference. The exact machine-readable identity of every productivity entry appears in the method catalog.
