This chapter introduces some popular methods in this area used by statisticians, demographers, and other quantitative methodologists in summarizing survival data. It focuses on Kaplan–Meier and Nelson–Aalen e
Although, there are some computational differences between Yule's Q and the ϕ coefficient, Bakeman, McArthur, and Quera concluded that in testing for group differences, the choice of one method versus the other has no impact on inference. Table I. An Example of a 2 × 2 Table with ...
