Question 82

Multiple Choice

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,what is the estimated probability of coronary heart disease for a 60-year-old individual? A) 0.5437 B) 0.2231 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.
