Examples of prior to posterior analysis using the data in Table 2. The x-axes display D' and the y-axes display the empirical estimate of the density function inferred with the program WinBugs 1.4. Figure (a) is the prior density of D' to measure the LD between the SNPs S1 and S2 that are at a distance of 3.2 kb. Figure (b) displays the posterior density, given the data in Table 1, and shows that data overwhelm the prior distribution when the distance is relatively small. Figure (c) is the prior density of D' to measure the LD between the SNPs S1 and S3 that are now more distant (364 kb). Figure (d) shows the posterior distribution, given the same data in Table 1, and shows now the relatively smaller effect of the data on the prior density.
