Figure A2
The horizontal axis is labeled “N clusters,” ranging from 2 to 10 with an interval of 2. The vertical axis is labeled “Indicators,” ranging from 0.2 to 0.8 with an interval of 0.2. Four lines are plotted on the graph, each representing a different clustering method, with the corresponding values. The orange line represents the “A S uppercase W lowercase w (0.2 over 0.32),” which starts near the indicator 0.32 at the cluster of 2, then follows a downward trend with some variation and ends below 0.2. The cyan line “H C (0.1 over 0.2),” which starts near the indicator 0.2 at the cluster of 2, then follows a downward trend with some variation and ends at the bottom right corner. The purple line “H G (0.61 over 0.87),” which starts near the indicator 0.6 at the cluster of 2, then follows an upward trend with some variation and ends at the top right corner. The green line “P B C (0.5 over 0.6),” which starts near the indicator 0.5 at the cluster of 2, then follows an upward trend towards the middle, then follows the downward trend, and ends above 0.5. Note: All numerical data values are approximated.Overview of partition quality indicators ASWw, HG, PBC and HC for N clusters. Source: Figure created by authors
