Pat Ferrel commented on MAHOUT-1853:
------------------------------------
If t-digest is more tolerant of "not having enough data" than fitting the
params of a normal dist then I'll do #1 and #2 now for 0.13. Then for #3 will
integrate t-digest as a way to calculate the threshold for #2 in the next
phase. #3 would be the release after, which would give us time to upgrade
t-digest or cut it loose and treat as a dependency, it's in the maven repos.
