Solve input(output)-oriented FDH
fdh(base = NULL, frontier = NULL, noutput = 1, orientation=1)
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). |
orientation |
Orientation of measurement. 1 for the input-oriented measure, and 2 for the output-oriented measure. |
The input (output) -oriented FDH is calculated.
A data frame of J1*1 dimention which shows efficiency scores.
