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. 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 linear equation,find the age of a person for which the estimated chances of having coronary heart disease are 50%? A) 47.8 years old B) 56.3 years old C) 45.5 years old D) 47.6 years old 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.
