Detailed Description
A class for multivariate principal component analysis using R to calculate p-values.
This class derives from the multi-correlative statistics algorithm and uses the covariance matrix and Cholesky decomposition computed by it. However, when it finalizes the statistics in learn operation, the PCA class computes the SVD of the covariance matrix in order to obtain its eigenvectors.
In the assess operation, the input data are
- projected into the basis defined by the eigenvectors,
- the energy associated with each datum is computed,
- or some combination thereof. Additionally, the user may specify some threshold energy or eigenvector entry below which the basis is truncated. This allows projection into a lower-dimensional state while minimizing (in a least squares sense) the projection error.
In the test operation, a Jarque-Bera-Srivastava test of n-d normality is performed.

Member Function Documentation
| static int vtkPCAStatisticsGnuR::IsTypeOf | ( | const char * | name | ) | [static] |
Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

| ) | [virtual] |
Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

| static vtkPCAStatisticsGnuR* vtkPCAStatisticsGnuR::New | ( | ) | [static] |
Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

| virtual vtkDoubleArray* vtkPCAStatisticsGnuR::CalculatePValues | ( | vtkIdTypeArray * | , |
| vtkDoubleArray * | |||
| ) | [protected, virtual] |
Calculate p-value. This will be overridden using the object factory with an R implementation if R is present.
