Math, stats, and miscellaneous type utilities
mathstatsorg.hammerlab.stats.Stats has APIs for ingesting numeric elements and outputting nicely formatted statistics about them; modeled after Apache commons-math DescriptiveStatistics.
As a bonus, it can ingest numbers in histogram-style / run-length-encoded format, supporting Long values as well for computations involving element counts from RDDs:
scala> import org.hammerlab.stats.Stats
scala> :paste
Stats.fromHist(
List[(Int, Long)](
1 → 10000000000L,
2 → 1000000000,
1 → 100,
2 → 1000000000
)
