Next, consider the regression problem with only ck as a predictor. Since ck is observed more often than is myopathy, this regression will be based on more cases than were used in the first two parts of this problem. Fit the logistic regression mean function with log(ck) as the only regressor beyond the intercept. Summarize results.
