Omitted variables problem

[Odongo Kodongo]

I'm trying to solve the omitted variables problem using the best projection reiterative truncated projected least squares approach (Leightner and Inoue, 2007). My original regression uses Poisson, so this is going to be an important robustness check. Unfortunately, I cannot find the relevant Stata command for this least-squares method. Can someone please assist? Thank you.

Don't think there is such a command. It looks like DEA is being used.
