    Modifier and Type | Method and Description
    --- | ---
    `EstimatedHistogram` | HistogramBuilder.`buildWithStdevRangesAroundMean()` See `HistogramBuilder.buildWithStdevRangesAroundMean(int)`
    `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.
