/**
 * @class   vtkPAutoCorrelativeStatistics
 * @brief   A class for parallel auto-correlative statistics
 *
 * vtkPAutoCorrelativeStatistics is vtkAutoCorrelativeStatistics 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:
 * This class was written by Philippe Pebay, Kitware SAS 2012.
