(a) Discuss the best suited measures of association under various measurement scales. A 20-year study of British male physicians (R. Doll and R. Peto, British Med. J., 2: 1525-1536, 1976) noted that the proportion wha died from lung cancer was 0.00140 per year for cigarette smokers and 0.00010 per year for nonsmokers. The proportion who died from heat disease was 0.00669 for smokers and 000413 for nonsmokers. i) Describe the association of smoking with lung cancer and with heart disease, using the coefficient of association, and the odds ratio. Interpret. i) Which response (lung cancer or heartdisease) is more strongly related to cigarette smoking?
