synopsis:
    Statistical measures for finite or infinite data streams.
description:
    Statistical measures for finite or infinite data streams.
    .
    All operations use numerically stable floating point arithmetic.
    Measurements can be performed over the entire input stream or on a sliding
    window of fixed or variable size.  Where possible, measures are computed
    online without buffering the input stream.
    .
    Includes\:
    .
    * Summary: length, sum, powerSum
    * Location: minimum, maximum, rawMoments, means, exponential smoothing
    * Spread: range, variance, deviations
    * Shape: skewness, kurtosis
    * Sample statistics, resampling
    * Probablity distribution: frequency, mode, histograms
    * Transforms: Fast fourier transform
