    Description

      skew and kurtosis should be parallelizable/lifftable by using a similar approach as std and var. See https://en.wikipedia.org/wiki/Algorithms_for_calculating_variance#Higher-order_statistics
      which has information on extending that approach to calculating the third and fourth central moments, needed for skew and kurtosis.
