Data.TDigest.Tree.NonEmpty

This is non empty version of Data.TDigest.TDigest, i.e. this is not a Monoid, but on the other hand, quantile returns Double not Maybe Double.

See Data.TDigest for documentation. The exports should be similar, sans non-Maybe results.

Example1 expression

>>> quantile 0.99 (tdigest (1 :| [2..1000]) :: TDigest 25)990.5

Example1 expression

>>> quantile 0.99 (tdigest (1 :| [2..1000]) :: TDigest 3)989.0...

t-Digest is more precise in tails, especially median is imprecise:

Example1 expression

>>> median (forceCompress $ tdigest (1 :| [2..1000]) :: TDigest 25)497.6...
