Simultaneous confidence intervals for the difference of two survival functions. (English) Zbl 0888.62107
Summary: In comparing two treatments with failure time observations, confidence bands for the “difference” of two survival curves provide useful information about a global picture of the treatment difference over time. We propose a rather simple procedure for constructing such simultaneous confidence intervals. Our technique can also be used in the one-sample case, which has been extensively studied in the literature.
