Abstract: A joint modeling framework is proposed that simultaneously models the ego's response and their multi-layer, longitudinal egocentric networks. The model consists of a set of mixed response models for the ego's response and ego-alter ties linked through shared random effects. It is discussed how to account for the heterogeneity in egocentric networks and how to address the computational challenges posed by the mixed responses and multivariate random effects. Data analysis reveals that perceived closeness with social ties is significantly associated with depressive symptoms.
