Table 2.

Results from a generalized estimating equation (GEE) testing the effects of asymmetries in the number of adult males (number of adult males in the focal group minus number of adult males in the other group) and intensity of use in the area surrounding the interaction’s location (focal group intensity of use/other group’s intensity of use) on the probability of winning across 4 timescales (3, 6, 9, and 12 months).
