This section contains reference documentation for the PERCENTILETDIGEST function. |
Returns the Nth percentile of the group using T-digest algorithm. An optional compression_factor can be specified to control the accuracy with a tradeoff in memory usage (i.e. higher compression_factor gives better accuracy but takes more memory). The default compression_factor is 100.
