Function documentation

void Print(Option_t* option = "") const
 print result of the fit, by default chi2, parameter values and errors
 if option "V" is given print also error matrix and correlation
TMatrixDSym GetCovarianceMatrix() const
 Return the covariance matrix from fit
 The matrix is a symmetric matrix with a size N equal to
 the total number of parameters considered in the fit including the fixed ones
 The matrix row and columns corresponding to the fixed parameters will contain only zero's
TMatrixDSym GetCorrelationMatrix() const
 Return the correlation matrix from fit.
 The matrix is a symmetric matrix with a size N equal to
 the total number of parameters considered in the fit including the fixed ones
 The matrix row and columns corresponding to the fixed parameters will contain only zero's
TFitResult(int status = 0)
 Default constructor for I/O
TFitResult(const ROOT::Fit::FitResult& f)
 constructor from an IFitResult
{}
virtual ~TFitResult()
