- \caption{Effect of each variable on (a) the probability of having entered a new research area and (b) the probability of having exited a research area, for each model. The reference model uses entropy as the diversity measure $D$ and the magnitude of intellectual capital as a measure of power $P$. Values indicate the mean posterior effect size and the 95\% credible interval. Significant effects are shown in bold.}
