c) The following R output is from fitting a logistic regression applied to this data. Use the output to: Nu11 deviance: 668.83 on 3 degrees of freedom Residual deviance: 642.40 on 2 degrees of freedom AIC: 646.4 Number of Fisher Scoring iterations: 6 i. calculate the fitted proportions who have the heart disease for each level of serum cholesterol. How are these related to the observed proportion of the heart disease from the above table? ii. test whether the serum cholesterol is associated with the heart disease. Use either the likelihood ratio test, based on the deviances, or the Wald test from the appropriate parameter estimate. iii. Why are the two analyses using poisson and logistic regression equivalent for studying the effect of serum cholesterol on the heart disease? c) The following R output is from fitting a logistic regression applied to this data.
