Bayesian Calculator estimating an interval or a credible region using the Markov-Chain Monte Carlo method to integrate the likelihood function with the prior to obtain the posterior function.

By using the Markov-Chain Monte Carlo methods this calculator can work with model which require the integration of a large number of parameters.

MCMCCalculator is a concrete implementation of IntervalCalculator. It uses a MetropolisHastings object to construct a Markov Chain of data points in the parameter space. From this Markov Chain, this class can generate a MCMCInterval as per user specification.

The interface allows one to pass the model, data, and parameters via a workspace and then specify them with names.

After configuring the calculator, one only needs to ask GetInterval(), which will return an ConfInterval (MCMCInterval in this case).

◆ SetKeysConfidenceAccuracy()

virtual void RooStats::MCMCCalculator::SetKeysConfidenceAccuracy ( Double_t epsilon )

inlinevirtual

Set the desired level of confidence-level accuracy for Keys interval determination.

When determining the cutoff PDF height that gives the desired confidence level (C_d), the algorithm will consider acceptable any found confidence level c such that Abs(c - C_d) < epsilon.

Any value of this "epsilon" > 0 is considered acceptable, though it is advisable to not use a value too small, because the integration of the Keys PDF sometimes does not have extremely high accuracy.

Definition at line 133 of file MCMCCalculator.h.

◆ SetKeysTerminationThreshold()

virtual void RooStats::MCMCCalculator::SetKeysTerminationThreshold ( Double_t delta )

inlinevirtual

When the shortest interval using Keys PDF could not be found to have the desired confidence level +/- the accuracy (see SetKeysConfidenceAccuracy()), the interval determination algorithm will have to terminate with an unsatisfactory confidence level when the bottom and top of the cutoff search range are very close to being equal.

This scenario comes into play when there seems to be an error in the accuracy of the Keys PDF integration, so the search range continues to shrink without converging to a cutoff value that will give an acceptable confidence level. To choose how small to allow the search range to be before terminating, set the fraction delta such that the search will terminate when topCutoff (a) and bottomCutoff (b) satisfy this condition:

TMath::Abs(a - b) < TMath::Abs(delta * (a + b)/2)
