Question: 15. Table 7.7 presents observed (Yi) and expected (Ei) cases of lip cancer in 56 counties in Scotland, which have been previously analyzed by Clayton

15. Table 7.7 presents observed (Yi) and expected (Ei) cases of lip cancer in 56 counties in Scotland, which have been previously analyzed by Clayton and Kaldor (1987) and Breslow and Clayton (1993). The table also shows a spatial covariate, xi, the percentage of each county’s population engaged in agriculture, fishing, or forestry (AFF), the observed standardized mortality ratio (SMR) for the county, 100Yi/Ei, and the the spatial relation of each county to the others via the indices of those counties adjacent to it. The raw data and the AFF covariate are mapped in Figure 7.13 on page 370.
