Using the WGCS data, posted on the book website, estimate the conditional odds-ratio for the effect of Type A temperament (dibpat) on CHD (chd69) using a logistic model to adjust for age, BMI, SBP, cholesterol levels, and smoking. Now use the margins command or data duplication to obtain estimates of the marginal odds-ratio and absolute risk difference. Do the conditional and marginal odds-ratios differ by much? Why or why not? Would you be willing to interpret the resulting estimates as causal? Why or why not?
