## Struct template p_square_cumulative_distribution_impl

boost::accumulators::impl::p_square_cumulative_distribution_impl — Histogram calculation of the cumulative distribution with the algorithm.

## Synopsis

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

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

      // construct/copy/destruct
      template<typename Args> p_square_cumulative_distribution_impl(Args const &);

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

## Description

A histogram of the sample cumulative distribution is computed dynamically without storing samples based on the algorithm. The returned histogram has a specifiable amount (num_cells) equiprobable (and not equal-sized) cells.
