A Julia Package for Estimating Stochastic Frontier Models
SFrontiers.jl provides commands for estimating various parametric stochastic frontier models in Julia. The commands estimate model parameters, calculate efficiency and inefficiency index, compute marginal effects of inefficiency determinants (if any), and with the option of bootstrapping standard errors of the mean marginal effects. Estimation methods include the maximum likelihood estimator (MLE) and the method of moments (MoM) estimator.
The package uses Optim.jl
as the main driver for the maximum likelihood estimation.
sfmodel_MoMTest()
for testing distribution assumptions and estimating model parameters using the method of moments (v0.2.1).Collaboration to add models is welcome!
Current Version. It has a detailed example (also available in Jupyter notebook) of using SFrontiers.jl
to conduct a stochastic frontier analysis.
