public class GetQuantilesFromDoublesSketch
extends org.apache.pig.EvalFunc<org.apache.pig.data.Tuple>
This UDF is to get a list of quantile values from an DoublesSketch given a list of
fractions or a number of evenly spaced intervals. The fractions represent normalized ranks and
must be from 0 to 1 inclusive. For example, the fraction of 0.5 corresponds to 50th percentile,
which is the median value of the distribution (the number separating the higher half
of the probability distribution from the lower half).
