Risk maps based on BYM model (lung cancer mortality in the province of Lecce, 1992–2001). MCMC estimates of posterior probability δ _i = Pr{θ _i > 1|Y} and relative risk θ _i were reported for each area: for δ _i a scale of 10 equidistant intervals was used, at variance with relative risks for which quintile based maps were drawn. The areas in which > 0.8 were highlighted, showing the last two digits of the Istat municipal code. See the legend of Table 2 for further details about Bayesian models used for relative risk estimation.
