boost::accumulators::impl::skewness_impl — Skewness estimation.
// In header: <boost/accumulators/statistics/skewness.hpp> template<typename Sample> struct skewness_impl : public { // types typedef ; // construct/copy/destruct (); // public member functions template<typename Args> () ; template<typename Archive> (, ); };
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:
where are the
-th moment and
the mean (first moment) of the
samples.
