Struct template p_square_cumulative_distribution_impl

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

  typedef iterator_range< typename histogram_type::iterator >              result_type;

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.
