Hi, I am using the KernSmooth package to estimate nonparametrically bivariate density functions. However, it seems that the bandwidths (one for each co-ordinate direction) have to be selected manually. This does not apply for the univariate case, for which dpik (included in KernSmooth) uses up-to-date plug-in rules.
Does anyone know about a package, or function, which estimates bandwidths for the BIVARIATE case, following, for instance, the plug-in methods suggested by Wand and Jones? I will appreciate your help a lot. Thanks, Emili References: Wand, M. P. and Jones, M. C. (1995). Kernel Smoothing. Chapman and Hall, London.
