Calculates order-m efficiency score with bootstrap algorithm
Description
Calculates order-m efficiency score (output, input and hyperbolic direction)
for a set of assessment points (xeval, yeval) depending on sample points (xobs, yobs),
using the initial algorithm of Cazals et al. (2002).
a matrix of size n2 x p, input of assessment points
yeval
a matrix of size n2 x q, output of assessment points
m
an integer, the number of selected firms
B
an integer, the number of replication
m.move
a boolean, to choose different values of m
Details
This function computes the algorithm initially proposed by Cazals et al. (2002).
If m.move=TRUE, different values of m are given as suggested by Daouia et al (2009).
Value
a data.frame object with the average mean order-m efficiency score and standard deviation associated:
output
output direction
output
output direction
input
input direction
input
input direction
hyper
hyperbolic direction
hyper
hyperbolic direction
