Linear regression analyses of the percent DNA methyaltion of each CpG site in the putative promoter region of estrogen receptor alpha in 14‐day‐old Eastern Bluebird offspring in the diencephalon and telencephalon with yolk testosteorne concentration as the predictor variable. Only one significant outlier was detected using Grubbs' outlier test in the residuals of the regression between percent DNA methylation of telencephalon CpG site 4 and yolk testosterone (G = 2.41, P < 0.01); however, whether linear regression (P = 0.72) or robust regression (P = 0.91) was used the significance of the outcome did not change, so the linear regression results are presented in the table
