Notes: Dependent variable is HWBI in 2009. The number of observations is 101. †p < 0.1, *p < 0.05, **p < 0.01, ***p < 0.001. Our models passed all diagnostics of regression assumptions. Variance inflation factors are tested to be less than 5 and the numbers inside and outside parentheses are coefficients and robust standard errors, respectively.
