boost::accumulators::impl::density_impl — Histogram density estimator.
// In header: <boost/accumulators/statistics/density.hpp> template<typename Sample> struct density_impl : public { // types typedef ; typedef ; typedef ; typedef ; // construct/copy/destruct template<typename Args> (); // public member functions template<typename Args> (); template<typename Args> () ; template<typename Archive> (, ); };
The histogram density estimator returns a histogram of the sample distribution. The positions and sizes of the bins are determined using a specifiable number of cached samples (cache_size). The range between the minimum and the maximum of the cached samples is subdivided into a specifiable number of bins (num_bins) of same size. Additionally, an under- and an overflow bin is added to capture future under- and overflow samples. Once the bins are determined, the cached samples and all subsequent samples are added to the correct bins. At the end, a range of std::pair is return, where each pair contains the position of the bin (lower bound) and the samples count (normalized with the total number of samples).
