◆ calculateFitFractionsWithCovarianceErrorPropagation()

FitFractionList ComPWA::Tools::FitFractions::calculateFitFractionsWithCovarianceErrorPropagation ( const std::vector< std::pair< IntensityComponent, IntensityComponent >> &  Components,
const ComPWA::Data::DataSet &  PhspSample,
const ComPWA::FitResult &  Result 
)

Calculates the fit fractions with errors via error propagation from the covariance matrix.

The gradients are calculated via numerical differentiation:

\[ f´(x) = \frac{f(x+h) - f(x-h)}{2h} + O(h^2) \]
