Quantlet: | deahull | |
Description: | returns the DEA (Data Envelopment Analysis) input efficiency score and efficient level of inputs for each DMU (Decision making unit) |
Usage: | dea = deahull (X, Y) | |
Input: | ||
X | n x p matrix, p inputs of n DMU's, allows only NONNEGATIVE values for its entries | |
Y | n x q matrix, q outputs of n DMU's, allows only NONNEGATIVE values for its entries | |
Output: | ||
dea.effscore | n x 1 vector, the input efficiency scores of DMU's | |
dea.efflevel | n x p matrix, the efficient level of inputs of DMU's |
