I have below model library(car)
data(Duncan) vif(lm(prestige ~ income + education - 1, data=Duncan)) With this, I am getting a warning message Warning message: In vif.default(lm(prestige ~ income + education - 1, data = Duncan)) : No intercept: vifs may not be sensible. Why for model with no intercept, vifs may not be sensible? ______________________________________________ [email protected] mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide https://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
