  • Constructor Details

    • SpFci

      public SpFci()
      The SpFci class represents a specific algorithm for structural learning called "Conditional Independence Test-based Fast Causal Inference" (SpFci). This class extends the AbstractBootstrapAlgorithm class and implements the Algorithm, UsesScoreWrapper, and TakesIndependenceWrapper interfaces.

    • SpFci

      public SpFci(IndependenceWrapper test, ScoreWrapper score)
      Constructor for the SpFci class.
      Parameters:
      test - The IndependenceWrapper object to be used for the algorithm.
      score - The ScoreWrapper object to be used for the algorithm.
