Correction to: The Weibull Fréchet distribution and its applications

Afify et al. [The Weibull Fréchet distribution and its applications, J. Appl. Stat., 43 (2016), pp. 2608–2626] defined and studied a new four-parameter lifetime model called the Weibull Fréchet distribution. They made some mistakes in presenting the log-likelihood function and the components of score vector. In this note, we will correct them.     

Observations of Adolescent Peer Group Interactions as a Function of Within‐ and Between‐Group Centrality Status

Observations of adolescent (n = 258; M age = 15.45) peer group triads (n = 86) were analyzed to identify conversation and interaction styles as a function of within‐group and between‐group centrality status. Group members' discussions about hypothetical dilemmas were coded for agreements, disagreements, commands, and opinions. Interactions during a hypothetical decision were rated for openness, dominance, aggression, and prosocial behavior. Hierarchical linear modeling revealed that higher within‐group status predicted more disagreements, commands, and less openness than lower within‐group status. Interactions showed that prosocial and aggressive behavior varied as a function of individual status in low‐status but not high‐status groups. Boys, but not girls, engaged in more openness in higher status groups. Results provide insights into peer socialization.
