Cook's distance
Dear useRs,
I have some trouble with the calculation of Cook's distance in R.
The formula for Cook's distance can be found for example here:
http://en.wikipedia.org/wiki/Cook%27s_distance
I tried to apply it in R:
> y <- (1:400)^2
> x <- 1:100
> lm(y~x) -> linmod # just for the sake of a simple example
