int.dea {nonparaeff}

Linear Programming for the Data Envelopment Analysis with Integer-valued Inputs.

Description

Solve input-oriented DEA under the CRS

Usage

int.dea(base = NULL, frontier = NULL, noutput = 1, intinput = 1,
orientation=1, epsilon = 1e-06)

Arguments

base

A data set for DMUs to be evaluated. A data frame with J1*(M+N) dimention, where J1 is the number of DMUs, M for the number of inputs, and N for the number of outputs.

frontier

A data set for DMUs to be used in constructing a production possibility set (PPS). A data frame with J2*(M+N) dimention, where J2 is the number of DMUs, M for the number of inputs, and N for the number of outputs.

noutput

The number of outputs (N).

intinput

The number of integer inputs.

orientation

Orientation of measurement. 1 for the input-oriented measure, and 2 for the output-oriented measure. This argument is ignored.

epsilon

Non-Armechidean number. Use the default value.

Details

The input-oriented IDEA under the CRS assumption is calcualted. See Kuosmanen and Matin (2009).

Value

A data frame of J1*(1+J1+N+M+Q+Q), which shows efficiency scores, optimal weightes, optimal slacks for outputs and inputs, optiaml slacks for integer-valued inputs, and optimal integer inputs.
