Struct template skewness_impl

boost::accumulators::impl::skewness_impl — Skewness estimation.

Synopsis

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

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

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

Description

The skewness of a sample distribution is defined as the ratio of the 3rd central moment and the -th power of the 2nd central moment (the variance) of the samples 3. The skewness can also be expressed by the simple moments:

Equation 1.11. 


where are the -th moment and the mean (first moment) of the samples.
