Smooth Non-Parametric Frontier Analysis
Description
Fitting of non-parametric production frontiers for use in efficiency analysis.
Methods are provided for both a smooth analogue of Data Envelopment Analysis (DEA) and a
non-parametric analogue of Stochastic Frontier Analysis (SFA). Frontiers are constructed for
multiple inputs and a single output using constrained kernel smoothing as in
Racine et al. (2009), which allow for the imposition of monotonicity and concavity constraints
on the estimated frontier.
