Is this option (number of nearest neighbors) translate-able into bandwidth?
In reading the kknn article, it seems like it might be but I'm still not
exactly sure how. Unfortunately this is an important issue as the end users
are used to using certain bandwidth values for their work.
It may be
If by chance you have an objective function you could automatically
calculate the optimum number of nearest neighbors by cross validation
eliminating the need to set it in the first place.

Thanks for your quick reply (on a weekend even!) I've looked through the
results of the search you recommended, and several related searches, and
don't see anything exceptionally helpful. Kernel regression is a relatively
new analysis for me; I apologize for needing a little more
What about kknn -- that was listed as having the triangular distribution?

Hi Brian,

Look at Loader's locfit package. You are likely to be pleasantly surprised.

I originally looked over kknn because I need to be able to specify a
bandwidth parameter. I am trying to replicate some previous non-R work in
R, so I can't stray to far from the procedure used there. In reading the
paper referenced in the docs, I see that kknn can reduce to the

You can specify the number of nearest neighbors.
