Remarks

Unlike the methods of the Univariate class, which by and large expect to work with sample data that is stored entirely within memory, this class is designed to compute the most important summary statistics on streamed data, i.e. individual data points which need only be presented once and may afterwards be discarded.

The Combine(SummaryStatistics, SummaryStatistics) method allows you to combine two SummaryStatistics objects formed by processing disjoint data streams to obtain a combined SummaryStatistics object which has accurate summary statistics for the combined data set.
