## Struct template tail_quantile_impl

boost::accumulators::impl::tail_quantile_impl — Tail quantile estimation based on order statistics (for both left and right tails)

## Synopsis

    // In header: <boost/accumulators/statistics_fwd.hpp>

    template<typename Sample, typename LeftRight>
    struct tail_quantile_impl : public accumulator_base {
      // construct/copy/destruct
      tail_quantile_impl(dont_care);

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

## Description

The estimation of a tail quantile with level based on order statistics requires the caching of at least the smallest or the largest samples, being the total number of samples. The largest of the smallest samples or the smallest of the largest samples provides an estimate for the quantile:

Equation 1.31.
