public class CTLuMeanMultipleAttributes<N,O extends NumberVector<?,?>>
extends AbstractNeighborhoodOutlier<N>

Mean Approach is used to discover spatial outliers with multiple attributes.

Implementation note: attribute standardization is not used; this is equivalent to using the AttributeWiseVarianceNormalization filter.
