Description

Class Summary

HyperLogLogPlusPlus	A UDF that applies the HyperLogLog++ cardinality estimation algorithm.
MarkovPairs	Accepts a bag of tuples, with user supplied ordering, and generates pairs that can be used for a Markov chain analysis.
Median	Computes the median for a sorted input bag, using type R-2 estimation.
Quantile	Computes quantiles for a sorted input bag, using type R-2 estimation.
QuantileUtil	Methods used by Quantile.
StreamingMedian	Computes the approximate median for a (not necessarily sorted) input bag, using the Munro-Paterson algorithm.
StreamingQuantile	Computes approximate quantiles for a (not necessarily sorted) input bag, using the Munro-Paterson algorithm.
VAR	Generates the Variance of a set of Values.
VAR.Final
VAR.Initial
VAR.Intermediate
WilsonBinConf	Computes the Wilsonian binomial proportion confidence interval
