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

Type Parameters:

D - Distribution type

All Superinterfaces:

DistributionEstimator<D>, MOMDistributionEstimator<D>

All Known Implementing Classes:

ExponentialMOMEstimator, GammaMOMEstimator, InverseGaussianMOMEstimator, NormalMOMEstimator
```
public interface MeanVarianceDistributionEstimator<D extends Distribution>
extends MOMDistributionEstimator<D>
```
Interface for estimators that only need mean and variance. These can implicitely (obviously) also handle full statistical moments.
