Fit Method Classes

Classes describing Fit Method functions.

Classes
class	ROOT::Math::BasicFitMethodFunction< FunctionType >
	FitMethodFunction class Interface for objective functions (like chi2 and likelihood used in the fit) In addition to normal function interface provide interface for calculating each data contrinution to the function which is required by some algorithm (like Fumili) More...
class	ROOT::Fit::Chi2FCN< FunType >
	Chi2FCN class for binnned fits using the least square methods. More...
class	ROOT::Fit::LogLikelihoodFCN< FunType >
	LogLikelihoodFCN class for likelihood fits. More...
class	ROOT::Fit::PoissonLikelihoodFCN< FunType >
	class evaluating the log likelihood for binned Poisson likelihood fits it is template to distinguish gradient and non-gradient case More...
