摘要: In economics, several parametric regression-based models have been proposed to measure the technical efficiency of decision making units (DMUs). However, problem misspecification restricts use these methods. this paper, symbolic regression is employed obtain approximate optimal production function automatically using genetic programming (GP). Monte Carlo simulation used compare performance data envelopment analysis (DEA), deterministic frontier (DFA) and GP-based DFA with respect three different functions sample sizes. The simulated results indicated that method has better than others nonlinear functions.
