  1. Dominance (restricted): one catastrophic incidence curve is always statistically above[below] another for a specified range of thresholds
  2. Non-dominance due to insignificance: catastrophic incidence curves where the difference between curves is not statistically significant
  3. Non-dominance due to intersections: catastrophic incidence curves that intersect and where difference between curves are statistically significant
  4. Average length of dominance/Power of test: average continuous threshold range over which dominance was observed; considered an indirect assessment of the overall power to test for dominance
