r.squared | R Documentation |
This function computes R squared or adjusted R squared for plm objects. It allows to define on which transformation of the data the (adjusted) R squared is to be computed and which method for calculation is used.
r.squared(object, model = NULL, type = c("cor", "rss", "ess"), dfcor = FALSE)

A numerical value. The R squared or adjusted R squared of the model estimated on the transformed data, e. g., for the within model the so called "within R squared".
