  • Constructor Details

    • CptInvariantMarginalCalculator

      public CptInvariantMarginalCalculator(BayesIm bayesIm, Evidence evidence)
      Constructs a new marginal calculator for the given updated Bayes IM. It is assumed that the first BayesIm encountered on calling the getParentIm() method recursively is the Bayes IM with respect to which conjunctions of the form P(V1=v1' and V2=v2' and ... and Vn=vn') should be calculated.
      Parameters:
      bayesIm - a BayesIm object
      evidence - a Evidence object
