Description-en: t-digest algorithm for on-line accumulation of rank-based statistics
This PostgreSQL extension implements t-digest, a data structure for on-line
accumulation of rank-based statistics such as quantiles and trimmed means.
The algorithm is also very friendly to parallel programs.
.
The accuracy of estimates produced by t-digests can be orders of magnitude more
accurate than those produced by previous digest algorithms in spite of the fact
that t-digests are much more compact when stored on disk.
