Enum Constant Summary
Enum ConstantsEnum ConstantDescriptionTied values are assigned the average of the applicable ranks.Tied values are assigned the maximum applicable rank, or the rank of the last occurrence.Tied values are assigned the minimum applicable rank, or the rank of the first occurrence.Tied values are assigned a unique random integral rank from among the applicable values.Ties are assigned ranks in order of occurrence in the original array. -

Enum Constant Details
-
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 unique random integral rank from among the applicable values.For example,
[1, 3, 4, 3]
is ranked as either[1, 2, 4, 3]
or[1, 3, 4, 2]
where the choice is random.The assigned rank will always be an integer, (inclusively) between the values returned by the
MINIMUM
andMAXIMUM
strategies.Use of a unique rank ensures that ties are resolved so that the rank order is stable.
