...(hat)it
and i get the residual by typing;
residuals(mdl1) ==> do i make mistake here or should i write another command
get the epsilon(hat), suppose i typed the correct command
than i save the residuals as a vector with
>resid<-mdl1$residuals
supposing that epsilon(hat) measures the TFP (TFPit=epsilon(it)), i need to
regress knowledge variables on it, such as "eco" and "RD" and i want to use
panel-data techniques in order to get the effect of eco and RD net of
unobserved heterogeneity.
so the theortically the model that i want to estimate is
TFPit=alpha0+alpha1(eco)...
