Hi all,
I have run a ridge regression as follows:
reg=lm.ridge(final$l~final$lag1+final$lag2+final$g+final$u,
lambda=seq(0,10,0.01))
Then I enter :

modified L-W estimator is 36.18617
You didn't show an example of how to recreate your problem, but
this shows up when a term in a model is a factor (or character) variable
with no variation in it. E.g.,
> d <- data.frame(y=1:10, x1=rep(3,10), x2=rep(c("Female","Male"),c(7,3)))
> lm(y ~ x1 + x2, data=d, subset = x2=="Female")
Just because it is possible to make a plot, doesn't mean it's a good idea.
It would depend on what you're trying to show. -- H

Hi Lucas,
You may find some of these examples useful (towards the end):
