Shown is a model predicting the probability of a female’s litter being killed in an infanticidal attack by dominant females in the first week after birth (GLMM, n = 57 females giving birth to 50 communal litters in 11 groups). The model was fitted using a binomial error structure and logit-link function and with female ID, litter, and group as random intercepts.
