Notes Robust standard errors in parentheses. Household income is a categorical variable where each bin is $5,000 in size. The lowest category, for instance, goes from 0 to $5,000. The second bin goes from $5,001 to $10,000, etc. The first four regressions are ordinary least squares. The final four regressions are probit regressions with marginal effects presented in the table above.
