Struct template non_coherent_weighted_tail_mean_impl

boost::accumulators::impl::non_coherent_weighted_tail_mean_impl — Estimation of the (non-coherent) weighted tail mean based on order statistics (for both left and right tails)


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

template<typename Sample, typename Weight, typename LeftRight> 
struct non_coherent_weighted_tail_mean_impl {
  // types
  typedef numeric::functional::multiplies< Sample, Weight >::result_type            weighted_sample;
  typedef numeric::functional::average< Weight, std::size_t >::result_type          float_type;

An estimation of the non-coherent, weighted tail mean is given by the weighted mean of the

Equation 1.30. 

smallest samples (left tail) or the weighted mean of the

Equation 1.31. 

largest samples (right tail) above a quantile of level , being the total number of sample and the sum of all weights:

Equation 1.32.
