A medical researcher is interested in assessing the probability of some symptoms of coronary heart disease (CHD) being present at a given age.For this reason he uses the following data collected on 100 individuals.   Thus,the variable under study is CHD that assumes a value of 1 if coronary heart disease is present,and a value of 0 otherwise.Using Excel and Minitab,the following linear and logistics regression equations have been estimated: Linear Regression:   = - 0.53796 + 0.02181Age Logistic Regression:   Using the logistic equation,what is the estimated probability of coronary heart disease for a 60-year-old individual? A)  0.4581 B)  0.3219 C)  0.7706 D)  0.7946 Thus,the variable under study is CHD that assumes a value of 1 if coronary heart disease is present,and a value of 0 otherwise.Using Excel and Minitab,the following linear and logistics regression equations have been estimated: Linear Regression: A medical researcher is interested in assessing the probability of some symptoms of coronary heart disease (CHD) being present at a given age.For this reason he uses the following data collected on 100 individuals.
