Comments

Principal Component Analysis (PCA) is used to reveal hidden generalizing characteristics of the analyzed process. The method is used for feature selection by selecting main components from the input data.

Properties

  Property name Brief description
The Analysis property determines analysis parameters.
The CalcCovariance property determines the method used to calculate the standard deviation.
The IncludeAverages property determines whether intraclass and total averages should be used as additional components.
The MatrixAlignmentType property determines type of centering for the input data matrix.
The MissingData property determines missing data treatment parameters.
The Objects property determines source data (a set of variables).
The P property returns eigenvectors of the principal components.
The ScoreType property determines the type of a condition applied to principal components.
The Statistics property returns eigenvalues and statistics.
The V property returns principal component values.
The VAdj property returns the principal component values calculated as linear combinations of source series and eigenvectors.
The Weights property sets weight coefficients for observations.
