    • getHistogram

      public int[] getHistogram(double[] levels)
      Description copied from interface: Statistics
      Returns the histogram for this statistics. The histogram bin count would be equal to number of levels, minus one; so that each i-th bin is the number of samples in [i-th, (i+1)-th) levels.
      Parameters:
      levels - levels
      Returns:
      histogram data

    • getRawData

      public Iterator<Map.Entry<Double,Long>> getRawData()
      Description copied from interface: Statistics
      Returns the raw data for this statistics. This data can be useful for custom postprocessing and statistics computations. Note, that values of multiple calls may not be unique. Ordering of the values is not specified.
      Returns:
      iterator to raw data. Each item is pair of actual value and number of occurrences of this value.
