Figure 5

Heatmaps displaying the difference of Rand statistic between conditional and unconditional clustering in the first set of simulations. Green cells denote negative values and hence conditional clustering produces clusters with lower accuracy compared to unconditional clustering. Red cells denote positive values and hence conditional clustering produces clusters with higher accuracy compared to unconditional clustering. Black cells show no difference. The intensity of the color shows the magnitude of the number as shown by the legend. The horizontal axis represents the number of simulated patters per cluster, and the vertical axis represents the variance.
