Re: [R] Bivariate kernel density bandwidth selection

I'm faar from knowledgeable on R or kernel density estimation (or many other statistical things for that matter), but allow me a simplistic suggestion: I remember that in a package I co-authored quite some time ago (chplot -- maybe you might have a look at what it does) we use bkde2D from the

[R] Bivariate kernel density bandwidth selection

I've been trying to implement bivariate kernel density estimation. For data like mine, function "kde" from package "ks" with bandwidth matrix derived by function "Hscv" seems like a very good choice. Unfortunately, Hscv seems unmanageably slow except for very small sample sizes (up to a few hund
