PCA Properties

The PCA type exposes the following members.

Properties
  NameDescription
Public propertyAllEigenvectors
(V) Matrix consisting of the set of all eigenvectors of covariance matrix, one eigenvector per column.
Public propertyCumulativeEnergy
(g) Vector of cumulative energy content for each eigenvector.
Public propertyEigenvalues
(d) Vector consisting of the set of all eigenvalues of CovarianceMatrix.
Public propertyInverseTransformation
(inverseW) PseudoInverse of Matrix of basis vectors, one vector per column, where each basis vector is one of the eigenvectors of CovarianceMatrix, and where the vectors in TransformationMatrix are a sub-set of those in AllEigenVectors.
Public propertyMeans
(u) Vector of empirical means, one mean for each column of the data matrix.
Public propertyNeedCenteringNewData
Specify this flag if you need new observations to be centered before transform in Transform \ InverseTransform
Public propertyOriginalVariablesCount
Variables count in source dataset.
(Inherited from FactorTransformation.)
Public propertyStatus
Method Status.
(Inherited from FactorTransformation.)
Public propertyTransformationMatrix
(W) Matrix of basis vectors, one vector per column, where each basis vector is one of the eigenvectors of CovarianceMatrix, and where the vectors in TransformationMatrix are a sub-set of those in AllEigenVectors.
Public propertyTransformedVariablesCount
Transformed components count.
(Overrides FactorTransformationTransformedVariablesCount.)
