public final Enum NaNStrategy

Class Inheritance

Strategies for handling NaN values in rank transformations.

MINIMAL - NaNs are treated as minimal in the ordering, equivalent to (that is, tied with) Double.NEGATIVE_INFINITY.
MAXIMAL - NaNs are treated as maximal in the ordering, equivalent to Double.POSITIVE_INFINITY
REMOVED - NaNs are removed before the rank transform is applied
FIXED - NaNs are left "in place," that is the rank transformation is applied to the other elements in the input array, but the NaN elements are returned unchanged.
FAILED - If any NaN is encountered in the input array, an appropriate exception is thrown

Since

2.0
