Quantlet: fdhull
Description: returns the FDH (free disposal hull) efficiency scores for each DMU (Decision Making Unit)

Reference(s):

Usage: effscore = fdhull(X,Y)
Input:
X n x p matrix, p inputs of n DMU's, allows only POSITIVE values for its entries
Y n x q matrix, q outputs of n DMU's, allows only POSITIVE values for its entries
Output:
effscore n x 2 matrix, the efficiency scores of DMU's the first column = input oriented scores the second column = output oriented scores

Example:
library("metrics")
nber96 = readcsv("nber96.csv", ",")
DMU = nber96[,1]
X = nber96[,2:5]
Y = nber96[,6]
fdh = fdhull(X,Y)
DMU~fdh

Result:
The efficiency scores for each DMU are listed:
