Estradiol is a sex hormone. It not only has a critical impact on reproductive and sexual function, but it also affects other organs, including bones. Using the dataset "estradl.dta," (under resources, homework files, estradl.dta) run a regression using Body Mass Index (BMI) as the independent variable, and estradiol levels (ES_1) as the dependent variable. Save the standardized residuals, unstandardized and standardized predicted values, and the mean and individual prediction intervals. After you run the regression, plot the scatterplot of the standardized residuals (y axis) and the standardized predicted values (x axis). Which of the following statements about heteroscedasticity (i.e. violation of the common variance assumption) is the best based on the output?
