Description |
TDigests are a biased quantile estimator designed to estimate the values of the quantiles of streaming data with high accuracy and low memory, particularly for quantiles at the tails (p0.1, p1, p99, p99.9). See https://github.com/tdunning/t‐digest/blob/master/docs/t‐digest‐paper/histo.pdf for an explanation of what the purpose of TDigests is, and how they work. |
