4. USING STATISTICS AND MODELING TO ANALYZE THREATS IN AN AREA OF INTEREST (AOI) – Part 1
Many threats have highly skewed distribution on the landscape – entirely absent in many areas with relatively rare high values (see Example 1).
EXAMPLE 1. Transportation Corridors – Divided Highways
THREAT SEVERITY – A RANKING OF THREAT DATA
The model uses a cumulative distribution function (CDF) to set a severity scale ranging from 0.0 to 1.0 for each threat. Users can see the relationship between the raw data of the threat and its severity ranking within the pool of non-zero data (see Example 2).
EXAMPLE 2. Cumulative Distribution Function –
Analysis Results
When the analysis results are equal to or greater than the threshold limit, the threat is predicted to occur and will be displayed in a map (see Example 3).
