Implementing FA-DEA and PCA-DEA in STATA

In general, the dimension reduction methods, such as FA and PCA, are implemented in statistical analysis software, but the data envelopment analysis is doing by DEA software. Simultaneously implementing FA-DEA and PCA-DEA all in STATA is puts forward, and an example is also listed. This approach will facilitate the process using FA-DEA and PCA-DEA in the practical application, and will provided a new solution in the STATA to design and application of data envelopment analysis.
