Fig. 3. Discontinuity index based on vector norm of gap sizes. Solid lines (left to right) represent sample sizes of n = 160, 120, 80, 60, 40, and 20. Dashed lines (left to right) represent example data sets with n = 101 (boreal forest birds), n = 63 (firm data SIC 226), n = 48 (SW cities 1890), n = 36 (boreal forest mammals), n = 35 (Everglades mammals), and n = 31 (Mediterranean mammals). Dots on dashed lines depict where the example data set vector norm is located on the cdf.
