Table 4.

Results of four negative binomial GLMMs examining the differences in individuals’: aggression given, aggression received, submissive status given and submissive status received, during the post-introduction compared to the pre-introduction period, across macaque groups that experienced a successful male introduction.

Outcome	Predictors
	Intercept	Age	Dominance rank	Relatedness coefficient	Stage (post- vs pre-introduction)
Aggression given	1.37**	−0.03	2.29**	−0.13	−0.82**
Aggression received	4.11**	−0.10	−1.81**	−0.09	−0.79**
Status given	4.99**	−0.06	−1.93**	−0.09	−0.49
Status received	1.86**	−0.03	3.46**	−1.15**	−0.61(*)

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 2-level nested random effect of categorical ‘group ID’ (level-2), and ‘year of observation’ (level-1).
