AbsoluteUncenteredCorrelationDistance (ELKI: Environment for DeveLoping KDD-Applications Supported by Index-Structures)

java.lang.Object
- elki.distance.AbstractNumberVectorDistance
- - elki.distance.correlation.AbsoluteUncenteredCorrelationDistance

All Implemented Interfaces:

Distance<NumberVector>, NumberVectorDistance<NumberVector>, PrimitiveDistance<NumberVector>
```
public class AbsoluteUncenteredCorrelationDistance
extends AbstractNumberVectorDistance
```
Absolute uncentered correlation distance function for feature vectors. This is highly similar to AbsolutePearsonCorrelationDistance, but uses a fixed mean of 0 instead of the sample mean.

Since:

0.7.0
