Struct template with_density_weighted_median_impl

boost::accumulators::impl::with_density_weighted_median_impl — Median estimation for weighted samples based on the density estimator.


// In header: <boost/accumulators/statistics_fwd.hpp>

template<typename Sample> 
struct with_density_weighted_median_impl : public accumulator_base {
  // construct/copy/destruct
  template<typename Args> with_density_weighted_median_impl(Args const &);

  // public member functions
  void operator()(dont_care);
  template<typename Args> result_type result(Args const &) const;
  template<typename Archive> void serialize(Archive &, const unsigned int);


The algorithm determines the bin in which the -th sample lies, being the total number of samples. It returns the approximate horizontal position of this sample, based on a linear interpolation inside the bin.
