concept

ridge regression

Details

This data is used in an exercise on regression with many explanatory variables, page 413 of second edition. Original authors assume a quadratic functional form.

Examples

data(factorial)
summary(factorial)
# non-Bayesian analysis:
fac.mod1 <- lm(conversion ~ temperature+ratio+contact+
                            I(temperature*ratio)+I(temperature*contact)+
                            I(ratio*contact)+I(temperature^2)+I(ratio^2)+I(contact^2), 
                  data=factorial)
