Posterior distributions p ( u _j , v _j |{ lⁿ| cⁿ =  j }). (a): Contour plots of the posterior distributions p(u _j ,v _j |{lⁿ|cⁿ = j}). For each group, we show an ellipse centred at the mean and enclosing 95% of the distribution. (b): Linear transformation of chronological age a, u _j a+v _j , for 100 pairs (u _j ,v _j ) sampled from p(u _j ,v _j |{lⁿ|cⁿ = j}) for Groups H (continuous blue) and SC (dashed-green), showing that uncertainty is higher at young and old ages and lower at middle ages.
