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 construct 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).
Details
The SBM under the CRS assumption is calculated. See Tone (2001).
Value
A data frame with (1+J1+M+N), which shows efficiency scores, optimal
weights, and optiaml input and output slacks.
