Boxplots of Selection and Influence Effects across Schools. Boxplots (Minimum, Maximum, 25th and 75th percentiles) for selection and influence effect parameter estimates β across all schools (n = 13). Significant coefficients are labeled with an asterisk, where a co-efficient is considered significant if the Snijders-Baerveldt test is less than 0.05 or the Fisher combination test is less than 0.025. For selection effects, coefficients correspond to the log-odds of a friendship tie being present vs. absent if the selection criterion is met. For influence effects, coefficients correspond to log-odds of a one-step increase in alcohol use frequency given a one-unit increase in the independent variable.
