EXAMPLE 3. Cumulative Distribution Function – Threat Severity
Transportation Corridors – Divided Highways
Users can adjust the default threshold for any threat. This example uses 0.3 as the threshold and shows the scaled results in the map. Using a CDF to derive severity scores provides visual results for threat exposure.
THREAT OCCURRENCE
If a threat value is above a set minimum threshold, it is predicted to occur. Otherwise, it is said to be absent.
Notice that everything in the color scale ranked 0.01 to 0.3 is no longer represented in the map (compare Examples 3 and 4).
