Struct template with_p_square_cumulative_distribution_median_impl

boost::accumulators::impl::with_p_square_cumulative_distribution_median_impl — Median estimation based on the cumulative distribution estimator.

Synopsis

// In header: <boost/accumulators/statistics/median.hpp>

template<typename Sample> 
struct with_p_square_cumulative_distribution_median_impl {
  // types
  typedef numeric::functional::average< Sample, std::size_t >::result_type float_type;    
  typedef std::vector< std::pair< float_type, float_type > >               histogram_type;
  typedef iterator_range< typename histogram_type::iterator >              range_type;    
  typedef float_type                                                       result_type;   

  // construct/copy/destruct
  with_p_square_cumulative_distribution_median_impl(dont_care);

  // public member functions
  void operator()(dont_care) ;
  template<typename Args> result_type result(Args const &) const;
};

Description

The algorithm determines the first (leftmost) bin with a height exceeding 0.5. It returns the approximate horizontal position of where the cumulative distribution equals 0.5, based on a linear interpolation inside the bin.
