class TMVA::MethodFDA: public TMVA::MethodBase, public TMVA::IFitterTarget


Function discriminant analysis (FDA). This simple classifier
fits any user-defined TFormula (via option configuration string) to
the training data by requiring a formula response of 1 (0) to signal
(background) events. The parameter fitting is done via the abstract
class FitterBase, featuring Monte Carlo sampling, Genetic
Algorithm, Simulated Annealing, MINUIT and combinations of these.

Can compute regression value for one dimensional output
