Table 1.
Comparisons of BClustLonG, BClustLonG0, MCLUST, EPGMM, and K-means in simulation settings. The numbers in each cell indicate the average adjusted Rand index (Avg.Rand) and the average number of clusters (Avg.Clust) estimated by each method under each scenario with standard deviations in parentheses.
