Figure 10From: Geostatistical analysis of disease data: estimation of cancer mortality risk from empirical frequencies using Poisson krigingImpact of population size and local variance on differences between estimates of cancer mortality risk. Top and bottom scattergrams illustrate the largest differences among mortality risks estimated for less densely populated counties. Middle row shows that the local and global empirical Bayes smothers yield similar shrinkage factor (kernel weight) for areas where the local variance s2(uα) is close to the global variance s2.Back to article page
