@hackage foldl-statistics0.1.1.0

Statistical functions from the statistics package implemented as Folds.

The use of this package allows statistics to be computed using at most two passes over the input data, one to compute a mean and one to compute a further statistic such as variance and nth central moments. All algorithms are the obvious implementation of Bryan O'Sullivan's statistics package imeplemented as Folds from the foldl package.
