The PCA axes are three of the five first principal components axes. Principal component analysis (PCA) of genome-wide panels of PS markers has become a widely popular method for examining evidence of population stratification in association studies. PCA is a general statistical method for transforming a vector of covariates into orthogonal axes, known...
