int KLFitter::LikelihoodTopLeptonJets_JetAngles::AdjustParameterRanges ( )

overrideprotectedvirtual

Adjust ranges of the parameters.

This either takes the parameter sigmas from the transfer functions, if m_flag_get_par_sigmas_from_TFs is set. Otherwise, a fixed sigma is used to calculate the parameter ranges. Then, SetParameterRange() is called to set the range. If m_flag_top_mass_fixed is set, the top mass will be fixed to the pole mass. Reimplemented with respect to LikelihoodTopLeptonJets::AdjustParameterRanges() due to additional parameters in Parameters.

Returns: An error code.

Reimplemented from KLFitter::LikelihoodTopLeptonJets.

int KLFitter::LikelihoodTopLeptonJets_JetAngles::CalculateLorentzVectors ( std::vector< double > const & parameters )

overrideprotectedvirtual

Update 4-vector values of the model particles.

This updates the internal variables, such as #bhad_fit_px or #thad_fit_m to the latest values from the fit. These variables are for example used in the log likelihood calculation. As opposed to LikelihoodTopLeptonJets::CalculateLorentzVectors(), the 4-vector values for the jets include the fitted angular information as well.

Returns: An error flag.

Reimplemented from KLFitter::LikelihoodTopLeptonJets.

void KLFitter::LikelihoodTopLeptonJets_JetAngles::DefineParameters ( )

overridevirtual

Define the parameters of the fit.

This calls BCModel::AddParameter() for all parameters in the enum Parameters. Reimplemented with respect to LikelihoodTopLeptonJets::DefineParameters() due to the additional parameters in Parameters.

Reimplemented from KLFitter::LikelihoodTopLeptonJets.

std::vector< double > KLFitter::LikelihoodTopLeptonJets_JetAngles::GetInitialParametersWoNeutrinoPz ( )

overridevirtual

Identical to LikelihoodTopLeptonJets::GetInitialParametersWoNeutrinoPz(), but adds the initial values for the additional angular parameters.

Returns: vector of initial values.

Reimplemented from KLFitter::LikelihoodTopLeptonJets.

double KLFitter::LikelihoodTopLeptonJets_JetAngles::LogLikelihood ( const std::vector< double > & parameters )

overridevirtual

The posterior probability definition, overloaded from BCModel.

With respect to LikelihoodTopLeptonJets::LogLikelihood(), this also adds resolutions terms for the jet eta and phi values.

Parameters

parameters A vector of parameters (double values).

Returns: The logarithm of the prior probability.

Reimplemented from KLFitter::LikelihoodTopLeptonJets.

std::vector< double > KLFitter::LikelihoodTopLeptonJets_JetAngles::LogLikelihoodComponents ( std::vector< double > parameters )

overridevirtual

The posterior probability definition, overloaded from BCModel.

Instead of the final log likelihood value as in LogLikelihood(), this returns all subcomponents.

Parameters

parameters A vector of parameters (double values).

Returns: A vector with the components of the logarithm of the prior probability. Its components are:
0) TF_bhad
1) TF_blep
2) TF_lq1
3) TF_lq2
4) TF_lep
5) TF_METx
6) TF_METy
7) TFeta_bhad
8) TFeta_blep
9) TFeta_lq1
10) TFeta_lq2
11) TFphi_bhad
12) TFphi_blep
13) TFphi_lq1
14) TFphi_lq2
15) BW_Whad
