vtkCorrelativeStatistics Class Reference
#include <vtkCorrelativeStatistics.h>
Detailed Description
A class for linear correlation.Given a selection of pairs of columns of interest, this class provides the following functionalities, depending on the chosen execution options: Learn: calculate extremal values, sample mean, and M2 aggregates (cf. P. Pebay, Formulas for robust, one-pass parallel computation of covariances and Arbitrary-Order Statistical Moments, Sandia Report SAND2008-6212, Sep 2008, http://infoserve.sandia.gov/sand_doc/2008/086212.pdf for details) Derive: calculate unbiased variance and covariance estimators, estimator of standard deviations, linear regressions, and Pearson correlation coefficient. Assess: given an input data set, two means and a 2x2 covariance matrix, mark each datum with corresponding relative deviation (2-dimensional Mahlanobis distance). Test: no statistical tests available yet.
