Unformatted text preview: Replot the KM curve using the loglog option to create a CI for the survival of the women in your study. By looking at your original KM plot, does it look like the curve for the men is contained in the CI? 3. You are given a small data set on survival times in two groups: group 1: 1, 1+, 2, 2+ group 2: 2, 3, 3+, 4 where + indicates a censored observation. (a) By hand, calculate and plot the KaplanMeier survival curves for each of these groups (plot on the same graph). (b) By hand, conduct the logrank test to compare the dierence in survival distribution. Which group has better survival? Is it signicant? 1...
