Question

14. A study population consists of people who visited a clinic on a walk-in basis and required a catheterization. The response, presence of coronary artery disease (CA), is dichotomous, as are the • explanatory variables, sex and ECG. The variable SEX takes the value o for females and 1 for males. ECG takes the value for lower ST segment depression and 1 for higher ST segment depression. Interpret the intercept from the logistic regression model below (I pt: logit(hi) = -1.1747 +1.2770 SEX + 1.0545 ECG

Answer 1

the value of intercept is -1.1747

if there is female visit in the clinic with lower ST segment depression ECG then the presence of coronery artery diseases will be negative i.e. around -1.1747
