Description

Extract the reference set for each DMU (inefficient DMUs and efficicent DMUs that are combination of other efficient DMUs) from a DEA model solution.

Usage

references(deasol,
           thr = 1e-4)

Arguments

deasol

Object of class dea obtained with some of the DEA model functions.

thr

Tolerance threshold (for avoiding missdetection of efficient DMUs due to roundoff errors)

Examples

# NOT RUN {
# Replication results model DEA1 in Tomkins and Green (1988).
data("Departments")
# Calculate Total income
Departments$Total_income <- Departments[, 5] + Departments[, 6]+Departments[, 7] 
data_DEA1 <- read_data(Departments,
                       inputs = 9,
                       outputs = c(2, 3, 4, 12))
result <- model_basic(data_DEA1, 
                      orientation = "io",
                      rts = "crs")
references(result) # Table 3 (p.157)
