Problem 5 Suppose that we are working with some doctors on heart attack patients. The dependent variable is whether the patient has had a second heart attack within 1 year (yes=1). We have two independent variables, one is age of the patient and the other is a score on anxiety scale (a higher score means more anxious). After applying logistic regression model, we have the following output: Deviance Residuals: Min 10 Median 30 Маx -1.064 0.000 0.000 0.000 1.446 Coefficients: Estimate Std. Error z value Pr (>|z|) (Intercept) Age Anxiety -471.441 223186.509 -0.002 0.998 6.394 3057.349 0.002 0.998 1.347 611.470 0.002 0.998 (Dispersion parameter for binomial family taken to be 1) Null deviance: 27.7259 on 19 degrees of freedom Residual deviance: AIC: 9.7087 3.7087 on 17 degrees of freedom Number of Fisher Scoring iterations: 23 a. Determine the estimated logistic regression equation. b. Calculate the odds ratio and interpret.
