This commit adds a new single value metric aggregation that calculates the statistic called median absolute deviation, which is a measure of variability that works on more types of data than standard deviation Our calculation of MAD is approximated using t-digests. In the collect phase, we collect each value visited into a t-digest. In the reduce phase, we merge all value t-digests, then create a t-digest of deviations using the first t-digest's median and centroids |
