Detailed Description

template<class parzen_dist_>
class bsta_parzen_adapt_bw_updater< parzen_dist_ >

A parzen window (kernel) updater.

If a new sample is within tol of the existing samples then don't insert. Otherwise if maximum number of samples has been reached, then compute a new bandwidth estimate based on the most probable fraction of the existing samples.
