Patterns of classification, based on most likely class memberships, across LPAs with 2–4 classes are summarized in Table 3. Largely the same groups of SNPs were classified into the null class across the 2- to 4-class models. Of the SNPs classified into the Signal class in the 2-class model, most (93.7%) were classified into the AD+ASP class (79.4%) or MD class (14.3%) in the 3-class model. A majority (89.1%) of SNPs in the 3-class AD+ASP class were classified into the AD (24.1%) or ASP (65.1%) classes in the 4-class model. 83.4% of the SNPs classified into the MD class of the 3-class model remained in the MD class of the 4-class model.
