Analytical bootstrap methods for censored data
Analytic bootstrap estimators for the moments of survival quantities are derived. By using these expressions recommendations can be made as to the appropriateness of bootstrap estimation under censored data conditions.
متن کاملBootstrap Methods for Truncated and Censored Data
For right censored data, Efron (1981) has shown that his “simple” and “obvious” methods of bootstrapping are equivalent. We explain why this equivalence no longer holds for truncated data. Wang (1991) generalized Efron’s “obvious” bootstrap method to data that are both left truncated and right censored, under the assumption that C ≥ T and C − T is independent of T , where T and C denote the (ge...
متن کاملDouble Bootstrap Confidence Interval Estimates with Censored and Truncated Data
Traditional inferential procedures often fail with censored and truncated data, especially when sample sizes are small. In this paper we evaluate the performances of the double and single bootstrap interval estimates by comparing the double percentile (DB-p), double percentile-t (DB-t), single percentile (B-p), and percentile-t (B-t) bootstrap interval estimation methods via a coverage probabil...
متن کاملModel based bootstrap methods for interval censored data
We investigate the performance of model based bootstrap methods for constructing point-wise confidence intervals around the survival function with interval censored data. We show that bootstrapping from the nonparametric maximum likelihood estimator of the survival function is inconsistent for both the current status and case 2 interval censoring models. A model based smoothed bootstrap procedu...
متن کاملInferential Procedures Based on the Double Bootstrap for Log Logistic Regression Model with Censored Data
Traditional inferential procedures based on the asymptotic normality assumption such as the Wald often produce misleading inferences when dealing with censored data and small samples. Alternative estimation techniques such as the jackknife and bootstrap percentile allow us to construct the interval estimates without relying on any classical assumptions. Recently, the double bootstrap became pre...
