Figure 1. Relative surveillance system performance. The performance of the 4 optimized surveillance systems (Island, Regional, Serotype, and Multi-objective) compared with 3 alternative designs (Population, Volume, and Diversity), with respect to estimating A) island-wide cases, B) serotype-specific cases, and C) regional cases. Each system contains 22 providers. Systems are ordered from highest to lowest performance in each graph. Performance is measured by average out-of-sample across 100 different 3-year periods, resulting from linear regression of target time series (e.g., island-wide cases) on time series of cases occurring within the specified surveillance system.
