static StatisticalSummary aggregate ( StatisticalSummary ... statistics ) { MathUtils . checkNotNull ( statistics ) ; return aggregate ( Arrays . asList ( statistics ) ) ; }
computes aggregated statistical summaries . < p > this method can be used to combine statistics computed over partitions or subsamples - i . e . , the returned statisticalsummary should contain the same values that would have been obtained by computing a single statisticalsummary over the combined dataset .
