PPML with high-dimensional fixed effects? #143
Comments
Hi Gabriel, You're right, calculating the PPML and friends in the end boils down to a series of pseudo de-meaning operations followed by OLS, which is what FixedEffects.jl is doing. I've implemented a version of this in GLFixedEffectModels.jl, maybe this is of use to you. I should add that bias correction for the incidental parameter problem (which is a nice way to kill off annoying seminar questions) is not yet implemented, and that I also haven't done a lot of testing. I think in the end it may make sense to put this into FixedEffectModels.jl, depending on how Matthieu and Erik feel about this. |
A quick update (I cannot believe that >2 years have passed!!) that I have been using a lot of the following, and it's been incredibly useful:

Glad to hear it's been useful! |
Thank you for the fantastic package!
I would like to ask whether there are any plans to implement a Poisson pseudo-maximum likelihood estimator with high-dimensional fixed effects, similar to STATA's PPMLHDFE?

Alternatively, is it possible to call FixedEffectModels from another package that estimates PPML?
