      Description

      The Percentile class can handle only in-memory data.
      It would be interesting to use an on-line algorithm to estimate quantiles as a storeless statistic.
      An example of such an algorithm is the exponentially weighted stochastic approximation described in a 2000 paper by Fei Chen , Diane Lambert and José C. Pinheiro "Incremental Quantile Estimation for Massive Tracking" which can be retrieved from CiteSeerX at http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.105.1580.
