|
EstimatedHistogram |
HistogramBuilder.buildWithStdevRangesAroundMean(int maxdevs)
Calculate the min, mean, max and standard deviation of the items in the builder, and
generate an EstimatedHistogram with upto
maxdev stdev size ranges either
side of the mean, until min/max are hit; if either min/max are not reached a further range is
inserted at the relevant ends. |
