What is Jaccards Coefficient?
Used for dichotomous ecosystems only: Jaccards coefficient is used to calculate similarity (or correlation) between the ecosystem model and the law matrix result (for each geopolitical jurisdiction). Use this result only when the ecosystem model entered contained dichotomous data (ones and zeroes). The higher (up to one) the result indicates a higher similarity between the ecosystem modeled and the laws associated with these elements. The coefficient closer to zero indicates little or no similarity between whether ecosystem linkages are accounted for in law. A negative result indicates that the relationships in the ecosystem are not accounted for in law, but the laws account for relationships between components of the ecosystem that are not modeled. What is G value? G value is another measure indicating the degree to which the ecosystem model relationships are accounted for in law. The higher the G (up to 1), the more gaps are found in the system. If G is zero, this means all ecosystem
