Apache Commons Math 3.6.1 · org.apache.commons.math3.stat.ranking.TiesStrategy

Strategies for handling tied values in rank transformations.

SEQUENTIAL - Ties are assigned ranks in order of occurrence in the original array, for example (1,3,4,3) is ranked as (1,2,4,3)
MINIMUM - Tied values are assigned the minimum applicable rank, or the rank of the first occurrence. For example, (1,3,4,3) is ranked as (1,2,4,2)
MAXIMUM - Tied values are assigned the maximum applicable rank, or the rank of the last occurrence. For example, (1,3,4,3) is ranked as (1,3,4,3)
AVERAGE - Tied values are assigned the average of the applicable ranks. For example, (1,3,4,3) is ranked as (1,2.5,4,2.5)
RANDOM - Tied values are assigned a random integer rank from among the applicable values. The assigned rank will always be an integer, (inclusively) between the values returned by the MINIMUM and MAXIMUM strategies.
