Table 3.

Ancien Régime life-history comparisons. Estimated mean contrast, and the fraction of posterior density above 0 (p), for each category of interest. Values close to p = 0 or p = 1 indicate strong evidence of a directional effect as indicated by the sign of the mean contrast. Values near 0.5 indicate no reliable difference.
