build_fsdea: Build fsdea problem

In adea: Alternate DEA Package

Build fsdea problem

Description

For the given input and output build the feature selection problem and return it.

Usage

build_fsdea(
  input,
  output,
  orientation = c("input", "output"),
  ninputs,
  noutputs,
  nvariables,
  lp = NULL
)

Arguments

input	A matrix or a data frame containing the inputs of the units to be evaluated, with one row for each DMU and one column for each input.
output	A matrix or a data frame containing the outputs of the units to be evaluated, with one row for each DMU and one column for each output.
orientation	Use "input" for input orientation or "output" for output orientation in DEA model. The default is "input".
ninputs	a number which is the number input features, variables, to be selected. Its default value is the number of input variables.
noutputs	a number which is the number output features, variables, to be selected. Its default value is the number of output variables.
nvariables	a number of total features, variables, to be selected. Only if both ninputs and noutputs are omitted. In other case it is ignored.

Details

This function implement the feature selection method in the article [Benitez-Pena, S., Bogetoft, P. and Romero Morales, D. *Feature Selection in Data Envelopment Analysis: A Mathematical Optimization approach* Omega, Elsevier BV, **2020**, Vol. 96, pp. 102068](http://www.sciencedirect.com/science/article/pii/S0305048318312131)

Note: As this function is mainly for internal use, to avoid unnecessary overload, it does not do an extensive check of the input parameters. Use the higher level fsdea function instead.
