What is QAP?
Used for non-dichotomous ecosystem models only: QAP stands for the Quadratic Assignment Procedure, which is a network correlation calculation to test the similarity between two symmetric matrices of the same size. This is the same calculation as used for the Mantel Test in ecology and geography. In this program, QAP is only useful in cases where the ecosystem model contains various strengths of relationships between elements (meaning the cells must contain more numbers than 1 and zero). The higher the QAP result (one is the highest, indicating an exact match between the ecosystem model and the law matrix) indicates that more of the relationships in the ecosystem may be accounted for in law. The closer the QAP result is to zero indicates that relationships in the ecosystem are not accounted for in law. The more negative (down to -1) the QAP result indicates that the relationships in the ecosystem are not accounted for in law, but the laws account for relationships between components of
