Boxplot of correlations between θ values estimated using the 20-probe difference model and θs estimated using different models, stratified by presence proportion. (a) 10-probe difference model; (b) 20-probe PM-only model; and (c) 20-probe MM-only model. The number of presence calls for a probe set in the 21 arrays and the subpopulation size for the six boxplots are: 0–3, 4,385; 4–7, 693; 8–11, 413; 12–15, 488; 16–19, 497; and 20–21, 323. Only 6,799 probe sets that have 20 probes are used.
