Each cell is the average proportion of solutions in which the resulting BIC was the best found for that data set. Bold values indicate the best ARI for the factor condition. RV, random values; ICEM, iteratively constrained EM; KM, k-means clustering; AHC, agglomerative hierarchical clustering; SS, sum score.
