## Struct template weighted_tail_quantile_impl

boost::accumulators::impl::weighted_tail_quantile_impl — Tail quantile estimation based on order statistics of weighted samples (for both left and right tails).

## Synopsis

template<typename Sample, typename Weight, typename LeftRight>
struct weighted_tail_quantile_impl {
typedef numeric::functional::average< Weight, std::size_t >::result_type float_type;
typedef Sample result_type;
weighted_tail_quantile_impl(dont_care);
template<typename Args> result_type result(Args const &) const;
};

## Description

An estimator of tail quantiles with level based on order statistics of weighted samples are given by (left tail) and (right tail), where

and

being the number of samples and the sum of all weights.
