You can load the pension data set in R by issuing the following command at the console data("pension"). This will load the data into a variable called pension. If R says the pension data set is not found, you can try installing the package by issuing this command install.packages("robustbase") and then attempt to reload the data.

Examples

data(pension)
plot(pension)summary(lm.p  <-    lm(Reserves ~., data=pension))
summary(lmR.p <- lmrob(Reserves ~., data=pension))
summary(lts.p <- ltsReg(Reserves ~., data=pension))
abline( lm.p)
abline(lmR.p, col=2)
abline(lts.p, col=2, lty=2)## MM: "the" solution is much simpler:
plot(pension, log = "xy")
lm.lp  <-    lm(log(Reserves) ~ log(Income), data=pension)
lmR.lp <- lmrob(log(Reserves) ~ log(Income), data=pension)
plot(log(Reserves) ~ log(Income), data=pension)
## no difference between LS and robust:
abline( lm.lp)
abline(lmR.lp, col=2)
