All eight MAMBAC curves had a rising cusp on the right side of the graph, which could result from either a low base rate taxon or positively skewed indicators. However, the average of these eight curves appeared considerably more similar to the simulated dimensional data than to the simulated taxonic data, and the CCFIs (Table 1) confirmed the similarity to the simulated dimensional data (Figure 1, top panel). Similarly, the eight MAXEIG graphs all appeared to rise on the right side of the graph without demonstrating a clear peak. Again, the average MAXEIG curve was more similar to the simulated dimensional data than to the simulated taxonic data, (Figure 1, middle panel). Finally, the L-Mode graph was unimodal and appeared more similar to the simulated dimensional data (Figure 1, bottom panel).
