Inline graphic — The simulations for a range of proportions of non-informative genes () under MAF difference and magnitude of SNP effect . The x-axis represents the proportions of non-informative genes. The y-axis represents the average purity given by NMF (red) and PCA-K (blue). The average purity of each method was shown as meanstandard error.
