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/weighted_median.hpp>

struct with_density_weighted_median_impl {
  // types
  typedef numeric::functional::average< Sample, std::size_t >::result_type float_type;

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.
