/**********************************************************************************
* Project : TMVA - a ROOT-integrated toolkit for multivariate data analysis *
* Package : TMVA *
* Root Macro: TMVAClassification *
* *
* This macro provides examples for the training and testing of the *
* TMVA classifiers. *
* *
* As input data is used a toy-MC sample consisting of four Gaussian-distributed *
* and linearly correlated input variables. *
* *
* The methods to be used can be switched on and off by means of booleans, or *
* via the prompt command, for example: *
* *
* root -l ./TMVAClassification.C\(\"Fisher,Likelihood\"\) *
* *
* (note that the backslashes are mandatory) *
* If no method given, a default set of classifiers is used. *
* *
* The output file "TMVA.root" can be analysed with the use of dedicated *
* macros (simply say: root -l <macro.C>), which can be conveniently *
* invoked through a GUI that will appear at the end of the run of this macro. *
* Launch the GUI via the command: *
* *
* root -l ./TMVAGui.C *
* *
