## Abstract One way of comparing simultaneous confidence intervals is to compare the length of individual confidence intervals. Simultaneous confidence intervals are the better the shorter individual confidence intervals are. It is shown that such comparison has no sense.
We derive a simultaneous conΓΏdence band for the ratio of two survival functions based on independent right-censored data. Earlier authors have studied such bands for the di erence of two survival functions, but the ratio provides a more appropriate comparison in some applications, e.g., in comparing
