Class Description

                                                                      
/*
  H-Matrix method, which is implemented as a simple comparison of      
  chi-squared estimators for signal and background, taking into        
  account the linear correlations between the input variables          

  This MVA approach is used by the DØ collaboration (FNAL) for the 
  purpose of electron identification (see, eg., 
  hep-ex/9507007). 
  As it is implemented in TMVA, it is usually equivalent or worse than
  the Fisher-Mahalanobis discriminant, and it has only been added for 
  the purpose of completeness.
  Two χ2 estimators are computed for an event, each one
  for signal and background, using the estimates for the means and 
  covariance matrices obtained from the training sample:

  

   
  

  TMVA then uses as normalised analyser for event (i) the ratio:
  (χS(i)2 − χB2(i))
  (χS2(i) + χB2(i)).
