In particular, we introduce a local bandwidth-choice method for the bands. Our approach uses empirical information about both the survival rate and the cen- soring rate, and employs undersmoothing to alleviate di±culties caused by bias. We use both Edgeworth expansion and numerical simulation, the former to de- velop a basic formula and the latter to modify it for general use. |
