## Synopsis

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

    template<typename N, typename Sample>
    struct rolling_moment_impl : public accumulator_base {
      // types
      typedef numeric::functional::fdiv< Sample, std::size_t, void, void >::result_type result_type;

      // construct/copy/destruct
      template<typename Args> rolling_moment_impl(Args const &);

      // public member functions
       BOOST_MPL_ASSERT_RELATION(N::value, 0);
      template<typename Args> void operator()(Args const &);
