[R] “log-rank test” and “Kaplan Meier actuarial plots (time to event curve)”

[Steven Stoline]

Dear All:



I do need your help with the “log-rank test” and “Kaplan Meier actuarial
plots (time to event curve)” with adding the confidence intervals bands for
the average score for each time to the curve of each group.


*Group variable:* 1 = group 1, 2 = group 2


*Time points:* time1, time2, time3, time4, time5


The goal is to compare the average scores of the two groups at each time
point and obtain the Kaplan Meier actuarial plots (time to event curve) for
the 5 time points for both groups in the plot.



Please use the following data for the test.


time1    time2    time3    time4    time5    groups
