Abstract
In the partial Koziol–Green regression model, the lifetime variable may be censored by two types of censoring variables. One is called informative because it satisfies the Koziol–Green assumption on proportionality of hazards and the other one is general. Braekers and Veraverbeke proposed a non-parametric estimator for the conditional lifetime distribution and obtained a Gaussian approximation for the corresponding process. In the present paper, we propose an appropriate resampling scheme and show that this leads to a valid bootstrap approximation for the process.
