Results of four negative binomial GLMMs examining the relationship between male introduction success and individuals’: aggression given, aggression received, submissive status given and submissive status received, across seven rhesus macaque groups (N = 156).

Outcome	Predictors
	Intercept	Age	Dominance rank	Relatedness coefficient	Introduction (successful vs unsuccessful)
Aggression given	2.02**	−0.01	2.03**	0.08	0.27(*)
Aggression received	4.60**	−0.07	−1.78**	0.09	0.31
Status given	5.19**	−0.04	−1.88**	−0.15	0.39
Status received	1.94**	0.02	3.54**	−1.33*	0.54*

Values in cells indicate β coefficients (effect sizes) for predictor variables (listed in the first row) for each of the four models. In each model, we included a 3-level nested random effect of categorical ‘group size’ (level-3), ‘group ID’ (level-2), and ‘year of observation’ (level-1).
