Comparison of % VIS in hot-spots for CIS, rate-threshold, z-threshold and BCP analyses for data sets with 200-2000 VIS. Boxplots indicate distributions of % VIS in hot-spots for 12 simulated data sets per data set size for the CIS, rate-threshold, z-threshold and BCP methods. Data set sizes are in increments of 100 for smaller data sets (200-600 VIS) to view performance when less data is available, and in increments of 200 otherwise. The CIS method (A) shows an increasing percentage of VIS in hot-spots with increasing data set size across all data set sizes. The z-threshold (C) and BCP (D) methods give the most consistent % VIS in hot-spots across data set sizes, with both methods giving most consistent results for data sets with ≥300 VIS.
