What is 'hcj'? Did you perhaps mean hsj()? The Sheather-Jones methods (or at least one of them) are implemented in packages stats (from MASS), KernSmooth and sm, and all are for Normal kernels. There is a concept of `equivalent' bandwidth for different kernels discussed in all good books on the subject of kernel density estimation, and this will enable you to convert the bandwidth to other kernels: see the help page for density (which shows the factor is very close to one for the triangular kernel).

If not, is there a way we could convert the bandwidth obtained by the default( I assume that the default is standard normal) in hcj(x,...) to other kernels. > I appreciate your help. > Thanks > Durai > > > --------------------------------- > > > [[alternative HTML version deleted]] > > ______________________________________________ > [email protected] mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html > -- Brian D.
