Evidence of contamination in dataset E. a γ _n , the estimated degree of contamination, and \(\bar {T}^{Y}_{n}\) are strongly correlated among females with a Pearson’s correlation coefficient r=0.953. b γ _n and O _n , the average log odds of SNP probes being outliers, are strongly correlated as well (r=0.954), including both males and females
