nCM_mpick: Select subsample size m from mlist !!!!Intended to be called from qDEA function!!!!

Description

Pulls associated set of nboot bootstrapped values and computes bias corected "s(m)" values. ** Uses Simar and Wilson (2011) suggested procedure for selecting m **

Usage

nCm_mpick(stat, boot, n, mlist, beta = 0.5, alpha = 0.05, CILag = 1)

Arguments

stat	DDEA or qDEA distance point estimate
boot	nboot by mcells matrix of bootstrapped DDEA and qDEA distance
n	Number of dmus in full reference set (X,Y)
mlist	Vector of subsample sizes
beta	Convergence rate. 0.5 => "root n" convergence
alpha	Alpha level for Simar-Wilson (2011) subsample size selection procedure
CILag	CILag level for Simar-Wilson (2011) subsample size selection procedure

Value

mpick = selected subsample size,

S = nboot by mcell matrix of s = stat(n) - (m/n)^beta(boot(m)-stat(n) bias corrected values for each sample size m

s = vector (of length nboot) of 'bias.corected' s-values for sample size 'mpick'

stat.bc = bias corrected point estimate of stat = mean(s)
