Influence.measures
I am using rw0641 with Windows 98. To list just the influential
repetitiones that result from "influence.measures", I am using the input
result <- lm(y~x)
and the code from the example in the help for "influence.measures"
INFLM <- function(result){
inflm <- influence.measures(result)
which(apply(inflm$is.inf,1,any))
}
It works fine up to now with the exception of Huber's data published in
Atkinson 1985:8 (Plots, Transformations and Regression)
Observation x y
1 -4 2.48
2 -3 0.73
3 -2 -0.04
