Hello,
I want to do a residue analysis of a Feasible Generalized Least Squares (FGLS) model, but I'm not sure how to do this for such models that work with dashboard data. In the case of OLS regressions, the plot(regressaools) function worked, but in this case, not.
My template is as follows:
fggls <- pggls(Y ~ X, data = panel_data, model = "random", effect = "time")
It was created using the plm package.
The graphics I want to get are similar to the graphics I uploaded.
Thank you!
