void TGo4Fitter::SetFitFunctionType ( Int_t  iFitFunctionType  )  [inline]

Set fitted function type for minimization. Possible values are: TGo4Fitter:ff_least_squares = 0 sum of difference squares between model and data; TGo4Fitter:ff_chi_square = 1 standard chi-square sum TGo4Fitter:ff_chi_Pearson = 2 Pearson chi-square for Poisson statistic TGo4Fitter:ff_chi_Neyman = 3 modified Neyman chi-square for Poisson statistic TGo4Fitter:ff_chi_gamma = 4 modified chi-square for Poisson statistic TGo4Fitter:ff_ML_Poisson = 5 -2Ln from maximum likelihood function for Poisson statistic TGo4Fitter:ff_user = 6 user function User function type should not be specified directly, but using SetUserFitFunction() method. More information about fit function types can be found in Go4Fit tutorial.

void TGo4Fitter::SetMemoryUsage ( Int_t  iMemoryUsage  ) 

Set value of memory usage. This parameter can be: 0 - no additional memory will be allocated in buffers 1 - buffers will be allocated only for data objects 2 - buffers will be used for all data and models objects 3 - individual setup for data and model objects will be used for memory allocaions

void TGo4Fitter::SetUserFitFunction ( TUserFitFunction  iFunc  )  [inline]

Set user-defined fitted function. Function should be global and has following signature: Double_t (*TUserFitFunction)(Int_t, Double_t*, Double_t*) First parameter - number of points, Second - array of data points, Third - array of model points. Function should return value, which will be MINIMIZED by fitter. If necessary maximization, fit function should return negative value.
