Mixed influence diffusion model fit of rate of docetaxel use over time by year. The model explained 99.2% of total observed variation. The coefficient for k 2 (= 0.462), the measure of internal influence, was 7.2x the magnitude of the coefficient for k 1 (= 0.064), consistent with the hypothesis that social dynamics played an important role in the diffusion of docetaxel.
