The Frailty Index Flai is a quantitative measure of biological aging based on 34 health variables. The figure below shows fitted prediction lines for a
main effect multiple regression model of Fl4 on age and an indicator variable for whether a person walks at least 30 minutes per day (Walker =1 if the
person walks 2 30 mins/day and O if not).
