Robust stochastic frontier using Cauchy distribution for noise component to measure efficiency of rice farming in East Java

Several studies have been conducted to estimate efficiency of rice farming in Indonesia. Those studies generally apply standard stochastic frontier (SF) model which assume that noise component has normal distribution. However, the normality assumption of noise is inadequate if the outliers are prese...
