  1. Shown are AIC and BIC values for the fit of the log-linear attachment function of Krapivsky’s model and the nonlinear one of Redner’s model to the maximally, daily, monthly, and yearly resolved APS citation data attachment rate, respectively. The best model (the smallest AIC/BIC value) for each level of resolution is indicated in bold. Redner’s model best describes the data at the three highest levels of resolution (maximal, daily, and monthly). Krapivsky’s model best describes the data at the lowest level of resolution (yearly).
