Dear K,
As I just confirmed, dfbetas() works in a model without an intercept, so you
should send more information about the problem that you apparently
encountered:
> mod <- lm(dist ~ speed - 1, data=cars)
> head(dfbetas(mod))
speed
1 -0.020499616
2 -0.003469201
3 -0.061492972
4 0.006084618
5 -0.031008553
6 -0.078358279
Regards,
John
