library(rDEA)
data("hospitals", package="rDEA")
 
## choosing inputs and outputs for analysis
firms = 1:50
Y = hospitals[firms, c('inpatients', 'outpatients')]
X = hospitals[firms, c('labor', 'capital')]
 
## Robust DEA with 1000 bootstrap iterations and variable returns-to-scale
di = dea.robust(X=X, Y=Y, model="input", RTS="variable", B=1000)
 
## robust estimates of technical efficiency for each hospital
