Question

Does anyone know about a R package that supports fixed effect, instrumental variable regression like xtivreg in stata (FE IV regression). Yes, I can just include dummy variables but that just gets impossible when the number of groups increases.

Thanks!

By “impossible,” do you mean “computationally impossible”? If so, check out the plm package, which was designed to handle cases that would otherwise be computationally infeasible, and which permits fixed-effects IV.

Start with the plm vignette. It will quickly make clear whether plm is what you’re looking for.

Update 2018 December 03: the estimatr package will also do what you want. It’s faster and easier to use than the plm package.
