  1. aSnijders-Baerveldt two-sided test [39].
  2. Parameter estimates β and standard error for stochastic actor-based model of the evolution of school friendships in the Add Health study. Coefficients correspond to the change in log-odds of a friendship nomination being present. Characteristics are bolded when the Fisher’s combination test yields a p-value less than 0.025.
