Capturing population structure in the CHAMACOS data. Presented are linear predictors of the first genotype-based PC using a the first two methylation PCs of the data, b the first two PCs calculated after applying a feature selection based on proximity of CpGs to nearby SNPs [21], c the first two PCs after adjusting the data for cell-type composition (adjusted methylation PCs), d the first two adjusted methylation PCs after excluding 167,738 probes containing SNPs from the data and e using the first two EPISTRUCTURE PCs
