Enum TiesStrategy
- All Implemented Interfaces:
Serializable
,Comparable<TiesStrategy>
,java.lang.constant.Constable
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.
