However, data are often collected from the more feasible prevalent cohort study, whereby diseased individuals are recruited through a cross-sectional survey and followed in time. In the absence of temporal trends in survival, we derive an efficient nonparametric estimator of the cumulative incidence based on such data and study its asymptotic notfall-verhuetung.info by: 5. Wang, M.-C. () Nonparametric Estimation from Cross-Sectional Survival Data. Journal of the American Statistical Association, 86, Nonparametric Estimation From Cross-Sectional Survival Data MEl-CHENGWANG* In many follow-up studies survival data are often observed according to a cross-sectional sampling scheme. Data of this type are subject to left truncation in addition to the usual right censoring. A number of characteristics and properties of the product.
Nonparametric estimation from cross-sectional survival data
Biometrika (), pp. 1–15 doi: /biomet/ass C Biometrika Trust Printed in Great Britain Nonparametric incidence estimation from prevalent cohort survival data BY MARCO CARONE Division of Biostatistics, School of Public Health, University of California Berkeley. Non-Parametric Estimation in Survival Models Germ´an Rodr´ıguez [email protected] Spring, ; revised Spring We now discuss the analysis of survival data without parametric assump-tions about the form of the distribution. 1 One Sample: Kaplan-Meier Our ﬁrst topic is non-parametric estimation of the survival function. If the. Cross-sectional sampling of survival data implies that one is only able to observe lifetimes corresponding to individuals “in progress” at a given time point t 0 (the cross-section date). That is, the individuals entering the sample are those who have already experienced the initiation of an event prior to time t notfall-verhuetung.info by: Nov 06, · Abstract. Survival data from prevalent cases collected under a cross-sectional sampling scheme are subject to left-truncation. When fitting an additive hazards model to left-truncated data, the conditional estimating equation method (Lin & Ying, ), obtained by modifying the risk sets to account for left-truncation, can be very inefficient, as the marginal likelihood of the truncation times Cited by: Wang M-C.
