estimator as a *function*. Therefore it actually makes a lot of sense and it is an activate research area in statistics. Please check these concepts before replying. > Date: Fri, 20 Jan 2012 12:05:10 -0800 > Subject: Re: [R] Estimation of the mode > From: gunter.ber...@gene.com >

You realize, I trust, that "the mode" of a continuous distribution has no meaning without prior specification of the distribution, which, for a fitted density estimate would mean specification of the fitting parameters (bandwidth, etc.) at a minimum. So perhaps you need to rethink what you are try

[R] Estimation of the mode

2012-01-20 Thread Javier xyz
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
