3.2.5. Ascertaining the Strength or Power of the Causality Relationships
For determining the power of the causality between the factors 1 and 2, the degree of closeness
between the relationship of two vectors > and ? is determined by calculating the similarity
(SM) between them. The similarity between > and ? determines the power or strength of the
causality relationships in SRMF. The distance between vectors determines the degree of
closeness between them (Kosko, 1985). To compute the value of similarity, the following
mathematical process can be used (Schneider et al., 1998).
