If is included (as in specification II), these values will be different from when is not included (specification I). Including an interaction term (III) or a quadratic term (IV) will also make …
In panels A, B and C the bottom part depicts population structure profiles of mutant co-operators at (blue) and of mutant defectors at (red). In panel D the bottom part depicts the …
Every point in the simplex represents a population state . The left down corner is , which has only groups with co-operators; the right down corner is , which has only groups with …
The three synergy conditions are that for all , that for all , and that increases with .
Defectors at only find themselves in groups with defectors, co-operators at only find themselves in groups with co-operators (not depicted in the figures). In the lower panel mutants …
The payoffs co-operators get, when they find themselves in groups according to would be compared to the payoffs defectors get when they are in a group of defectors only in order to determine …
The and according to the regression method coincide with each other at (middle panel, dotted lines) but do not coincide with the true (solid red) and (solid blue). The according to …
Inclusive fitness there is . Section X specifies the for this example.
