  "Description": "The t-Digest construction algorithm, by Dunning, (2019)\n<doi:10.48550/arXiv.1902.04023>, uses a variant of\n1-dimensional k-means clustering to produce a very compact data\nstructure that allows accurate estimation of quantiles. This\nt-Digest data structure can be used to estimate quantiles,\ncompute other rank statistics or even to estimate related\nmeasures like trimmed means. The advantage of the t-Digest over\nprevious digests for this purpose is that the t-Digest handles\ndata with full floating point resolution. The accuracy of\nquantile estimates produced by t-Digests can be orders of\nmagnitude more accurate than those produced by previous digest\nalgorithms. Methods are provided to create and update t-Digests\nand retrieve quantiles from the accumulated distributions.",
