Package dk.alexandra.fresco.stat.outlier

Class MahalanobisDistance

java.lang.Object
dk.alexandra.fresco.stat.outlier.MahalanobisDistance
All Implemented Interfaces:
dk.alexandra.fresco.framework.builder.Computation<ArrayList<dk.alexandra.fresco.framework.DRes<dk.alexandra.fresco.lib.fixed.SFixed>>,​dk.alexandra.fresco.framework.builder.numeric.ProtocolBuilderNumeric>
public class MahalanobisDistance
extends Object
implements dk.alexandra.fresco.framework.builder.Computation<ArrayList<dk.alexandra.fresco.framework.DRes<dk.alexandra.fresco.lib.fixed.SFixed>>,​dk.alexandra.fresco.framework.builder.numeric.ProtocolBuilderNumeric>
Compute the Mahalanobis Distance of all samples in a data set. This may be used to detect outliers in the data set which may be filtered out obliviously (see FilteredStatistics before using the data set for analysis.
