| CovarianceMatrixBuilder |
Interface for computing covariance matrixes on a data set.
|
| EigenPairFilter |
The eigenpair filter is used to filter eigenpairs (i.e. eigenvectors
and their corresponding eigenvalues) which are a result of a
Variance Analysis Algorithm, e.g.
|
| Class | Description |
|---|---|

Parameterization class.
|
| FilteredEigenPairs |
Encapsulates weak and strong eigenpairs that have been filtered out
by an eigenpair filter.
|

eigenpairs, where n is a user specified number.
|
| FirstNEigenPairFilter.Parameterizer |

|
| LimitEigenPairFilter |
The LimitEigenPairFilter marks all eigenpairs having an (absolute) eigenvalue
below the specified threshold (relative or absolute) as weak eigenpairs, the
others are marked as strong eigenpairs.

their eigenvalues and marks the first eigenpairs, whose sum of eigenvalues is
higher than the given percentage of the sum of all eigenvalues as strong
eigenpairs.
|
| PercentageEigenPairFilter.Parameterizer |
Parameterization class.
|
| ProgressiveEigenPairFilter |

eigenvalues and marks the first eigenpairs who are a certain factor above the
average of the remaining eigenvalues.
|
| RelativeEigenPairFilter.Parameterizer |
Parameterization class.
|
| SignificantEigenPairFilter |
The SignificantEigenPairFilter sorts the eigenpairs in descending order of
their eigenvalues and chooses the contrast of an Eigenvalue to the remaining
Eigenvalues is maximal.
