TMVA -Toolkit for Multi Variate Analysis

File Release Notes and Changelog

Release Name: TMVA-v4.0.1

Notes:
Release v4.0.1 (newest):

  - "Spectator" variables can be defined now which are computed just as the input variables 
    and which are written out into the TestTree, but which don't participate in any 
    MVA calculation (useful for correlation studies).

  - New booking option "IgnoreNegWeightsInTraining" to test the effect of events with 
    negative weights on the training. This is especially useful for methods, which do 
    not properly deal with such events.

  - Bug fixes:

    - Fixed regression bug in VariableNormalizeTransform (Use number of targets from 
      Event instead of DataSet) 

    - Fixed Multitarget-Regression in PDEFoam, foam dimensions were miscalculated

    - Added writing of targets to the weight files in regression mode to fix problems 
      in RegressionApplication

    - Added missing standard C++ header files missing to some classes, which lead to 
      compilation failures on some architectures (thanks to Lucian Ancu, Nijmegen, for 
      reporting these).

    - Added checks for unused options to Factory and DataSetFactory configuration options 
      interpretation. Will now complain if wrong option labels are used.

    - Fixed standard creation of correlation matrix plots

    - Fixed internal mapping problem giving a fatal error message when destroying and 
      recreating the Factory. 

    - A number of non-intrusive modifications required for integration into ROOT v5.23
