Figure 7From: A probabilistic model of biological ageing of the lungs for analysing the effects of smoking, asthma and COPDPosterior distributions p ( u j a + v j |{ ln| cn = j }) over all ages. Posterior distributions p(u j a + v j |{ln|cn = j}) for age a in the range 20–80 years at 5-year step-size. Each rectangle is centred at the mean and its length equals 2 ×1.96 times the standard deviation.Back to article page
