  1. Estimation of regression coefficients with "robust" standard errors (S.E.), chi-squares, and p-values.
  2. # gender ≡ 1 if subject is male and 0 if otherwise.
  3. &race/ethnicity ≡ 1 if subject is Black and 0 if otherwise.
  4. @ parent ≡ 1 if subject had parents or a single parent as guardian(s), and 0 if otherwise.
