void Add(RooArgSet& entry, Double_t nllValue, Double_t weight = 1.0)

void AddWithBurnIn(RooStats::MarkovChain& otherChain, Int_t burnIn = 0)

 Discards the first n accepted points.

void Add(RooStats::MarkovChain& otherChain, Double_t discardEntries = 0.0)

 Discards the first entries. This is different to the definition of
 burn-in used in the Bayesian calculator where the first n accepted
 terms from the proposal function are discarded.

THnSparse* GetAsSparseHist(RooAbsCollection* whichVars = NULL) const

 Get a clone of the markov chain on which this interval is based
 as a sparse histogram.  You own the returned THnSparse*

RooRealVar* GetNLLVar() const

 get a clone of the NLL variable

{ return (RooRealVar*)fNLL->Clone(); }

RooRealVar* GetWeightVar() const

 get a clone of the weight variable
