◆ ApplyCovarianceMatrix()

void RooAbsMinimizerFcn::ApplyCovarianceMatrix ( TMatrixDSym & V )

Set different external covariance matrix.

Apply results of given external covariance matrix.

i.e. propagate its errors to all RRV parameter representations and give this matrix instead of the HESSE matrix at the next save() call

Definition at line 397 of file RooAbsMinimizerFcn.cxx.

◆ applyEvalErrorHandling()

double RooAbsMinimizerFcn::applyEvalErrorHandling ( double fvalue ) const

protected

Apply corrections on the fvalue if errors were signaled.

Two kinds of errors are possible: 1. infinite or nan values (the latter can be a signaling nan, using RooNaNPacker) or 2. logEvalError-type errors. Both are caught here and fvalue is updated so that Minuit in turn is nudged to move the search outside of the problematic parameter space area.
