Good evening!
I need to run a regression with the model FGLS - Feasible Generalized Least Squares, however, I only found a package capable of running it, RFGLS ().
But I'm a beginner, both in R and in econometrics. Anyone who has ever used this package could give me some explanations about it?
I have already read his description on Cran, but I still can not execute.
Thank you in advance!
