Dear all,
I've just migrated from STATA to R for runing panel regressions and I was
very happy to discover the plm package. However, I have a problem when
trying to access the "Total Sum of Squares" and "Residual Sum of Squares" on
this output:
> summary(output)
Oneway (individual) effect Within Model
Call:
plm(formula = Y ~ X1 + X2, data = db, model = "within")
Unbalanced Panel: n=10, T=9-11, N=108
Residuals :
Min. 1st Qu. Median 3rd Qu. Max.
-6.500 -2.200 -0.374 1.550 8.730
Coefficients :
Estimate Std. Error t-value Pr(>|t|)
X1 113.302650 8.517736 13.302 <2e-16 ***
X2 -0.084414 0.109625 -0.770 0.4432
---
Signif. codes: 0 ‘***’ 0.001 ‘**’ 0.01 ‘*’ 0.05 ‘.’ 0.1 ‘ ’ 1
Total Sum of Squares: 3208.3
Residual Sum of Squares: 1059.6
F-statistic: 97.3365 on 2 and 96 DF, p-value: < 2.22e-16
I would like to do so because I'm running some hundreds times a similar
regression and I want to store those results in a vector and then plot them.
I've tried to do so with
>summary(output)[]
but neither the "Total Sum of Squares" or the "Residual Sum of Squares" are
on the list.
I would be glad if somebody can help me.
Thank you very much!
Eduardo Marinho.
