java.lang.Objectweka.core.NormalizableDistance
weka.core.ChebyshevDistance
public class ChebyshevDistance
Implements the Chebyshev distance. The distance between two vectors is the greatest of their differences along any coordinate dimension.
For more information, see:
Wikipedia. Chebyshev distance. URL http://en.wikipedia.org/wiki/Chebyshev_distance.

}
Valid options are:
-D Turns off the normalization of attribute values in distance calculation.
-R <col1,col2-col4,...> Specifies list of columns to used in the calculation of the distance. 'first' and 'last' are valid indices. (default: first-last)
-V Invert matching sense of column indices.
