Solve input-oriented DEA under the CRS
int.dea(base = NULL, frontier = NULL, noutput = 1, intinput = 1, orientation=1, epsilon = 1e-06)
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. |
The input-oriented IDEA under the CRS assumption is calcualted. See Kuosmanen and Matin (2009).
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.
