Nonparametric Inference for Copulas and Measures of Dependence Under Length-Biased Sampling and Informative Censoring
长度偏倚抽样与信息性删失下 Copula 及依赖度量的非参数推断
Length-biased data are often encountered in cross-sectional surveys and prevalent-cohort studies on disease durations. Under length-biased sampling subjects with longer disease durations have greater chance to be observed. As a result, covariate values linked to the longer survivors are favored by the sampling mechanism. When the sampled durations are also subject to right censoring, the censoring is informative. Modeling dependence structure without adjusting for these…
