Hi all,

I am trying to estimate the mode of a 4-dimensional nonparametric density estimator (any) using a sample of size n=10,000.  I have tried using the package 'ks' and 'np' but they are extremely slow;  this is related to the estimation of the bandwidth matrix.  I also checked the package 'modeest' but it contains only methods for univariate distributions.   I am only interested in the mode.   Any suggestion?

Thanks in advance.

Kind regards.
