12.116 You are asked to develop a multiple regression model that indicates the relationship between a person’s physical characteristics and the daily cost of food (daily cost). The predictor variables to be used are a doctor’s diagnosis of high blood pressure (doc bp), the ratio of waist measure to obese waist measure (waistper), the body mass index

(BMI), whether the subject was overweight (sr overweight), male compared to female (female), and age (age). Also, the model should include a dummy variable to indicate the effect of first versus the second interview.

a. Estimate the model using the basic specification variables indicated here.

b. Estimate the model again, but in this case include a variable that adjusts for immigrant versus native person (immigrant).

c. Estimate the model again, but in this case include a variable that adjusts for single status versus a person with a partner (single).

d. Estimate the model again, but in this case include a variable that adjusts for participation in the food stamp program (fsp).
