In all cases, the data are random samples from the freely-available NHANES dataset, and the variables used are;

The data are available as comma-separated files; (missing values are denoted “.”)

Regression analyses make the standard assumptions that the mean model is correctly specified, and (for linear regression) that the variance of outcomes is constant with respect to covariates.
