Result of clustering. Algorithms in the top row clustered X₄ at the last step, while it was clustered at the before the last step for algorithms in the bottom row. Algorithms in the left column clustered X₆ with {X₃, X₅}, while X₆ was clustered with {X₁, X₂} for the algorithms in the right column. Parts in grey correspond to clustering steps that were not performed by BayesCovAuto or BayesCorrAuto in (G1), or Bic in (G3).
