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 ------------------------------ John Fox, Professor Department of Sociology McMaster University Hamilton, Ontario, Canada web: socserv.mcmaster.ca/jfox > -----Original Message----- > From: r-help-boun...@r-project.org [mailto:r-help-boun...@r-project.org] On > Behalf Of Kutlwano Ramaboa > Sent: January-14-09 6:40 AM > To: r-help@r-project.org > Subject: [R] dfbetas without intercept > > > Hello > > I am running a regression without the intercept, and want to compute dfbetas. > How do I do this?
