For example, we want to find the best location for installing the wildlife sing. One of the best ways used is a kernel density estimation, according to some research, but finding the best radius is very important. I want to know which software could be useful for this?
Hi, may be the package for R adehabitatHR might suits for your needs.
Definitely try to stay in R. Library {ks} provides good bandwidth estimators. I tried quickly to make an example. Is not fully worked out. If a lot of people want to use it, we might include a wrapper in our library {move}. Good luck.
library(ks) #this is the library that provides more smoothing algorithms than adeHabitatHR the other library we should look into at some stage is KernSmooth
library(move) #for sample data

If you want alternatives to R packages:
1. Home Range Tools for Arc 9 provides good control over bandwidth selection and informs you if certain methods (e.g. LSCV) fail to select a bandwidth. It also allows you to incrementally increase or decrease the reference bandwidth. Art Rodgers (the author) is very helpful, although many forums already answer most questions about the software. http://flash.lakeheadu.ca/~arodgers/hre/
2. GME (new version of Hawth's tools) works with R and has great functionality, and "newer" methods of bandwidth selection. http://www.spatialecology.com/gme/
Hi, if you're looking for a powerful (multivariate/univariate) bandwidth selector in Matlab, you might find this useful:
