A multivariate linear regression model was constructed with monthly amount willing to pay for prevention as the dependent variable. A positive coefficient indicated a larger willingness to spend on preventative associated with increased explanatory variable (monetary units = 20 Reais increments). Model statistics: r² = 0.06, df = 150, mean square = 4.366, F statistic = 2.272.
