An Efficient Data Envelopment Analysis with Large Data Set in Stata

In this presentation, the author presents an approach to improve the computational efficiency of Data Envelopment Analysis(DEA) with large data set in Stata. Since the author written "dea" program in Stata was presented in the DC09 Stata conference, the author reviewed various comments and requests by the Stata users and updated the code significantly in terms of computation time and model variants. The presentation illustrates an approach to reduce the computation time and improve the accuracy of DEA results using the 5 inputs and 1 output data set of 365 DMUs.
