* @class vtkPPCAStatistics
* @brief A class for parallel principal component analysis
*
* vtkPPCAStatistics is vtkPCAStatistics subclass for parallel datasets.
* It learns and derives the global statistical model on each node, but assesses each
* individual data points on the node that owns it.
*
* @par Thanks:
* Thanks to Philippe Pebay, David Thompson and Janine Bennett from
* Sandia National Laboratories for implementing this class.
