Data envelopment analysis (DEA) is a popular non-parametric approach to examine performance and productivity of airlines; however, it could not provide statistical information such as confidence intervals on the estimated efficiency scores. We combined stochastic frontier DEA into single framework disentangle noise ‘pure’ inefficiency from scores accordingly for Monte-Carlo simulation verified ...

The paper considers estimating a parameter β that defines an estimating function U.y,x,β/ for an outcome variable y and its covariate x when the outcome is missing in some of the observations.We assume that, in addition to the outcome and the covariate, a surrogate outcome is available in every observation. The efficiency of existing estimators for β depends critically on correctly specifying t...
