Note. The table reports the estimation results of equation (3) for the group of retired women and men estimated via the random effect regression. The results of individual-effect F-statistics justify this procedure, which includes the individual effect dummies. The dependent variable is BMI30, a dummy variable, which equals one for Type I obesity (BMI ≥ 30) and zero otherwise. The stepwise procedure gradually omits variables with coefficients for whom . Variance inflation factor (VIF) is a measure for collinearity among independent variables. VIF < 10 implies low collinearity. Robust values are given in parentheses. . . .
