Table 2.

Summary of generalized linear model to test the effects of dominance rank of the mother, sex of the orphaned infant, age of the orphaned infant (days), and number of caregivers of the orphaned infant on duration of orphaned infant survival (days). Duration of orphaned infant survival is modeled as a Poisson distribution with logarithmic link function
