Comparing center-specific cumulative incidence functions
Springer Science and Business Media LLC - Tập 22 - Trang 17-37 - 2015
Ludi Fan, Douglas E. Schaubel
The competing risks data structure arises frequently in clinical and epidemiologic studies. In such settings, the cumulative incidence function is often used to describe the ultimate occurrence of a particular cause of interest. If the objective of the analysis is to compare subgroups of patients with respect to cumulative incidence, imbalance with respect to group-specific covariate distributions...... hiện toàn bộ
Nonparametric quasi-likelihood for right censored data
Springer Science and Business Media LLC - Tập 17 - Trang 594-607 - 2011
Lili Yu
Quasi-likelihood was extended to right censored data to handle heteroscedasticity in the frame of the accelerated failure time (AFT) model. However, the assumption of known variance function in the quasi-likelihood for right censored data is usually unrealistic. In this paper, we propose a nonparametric quasi-likelihood by replacing the specified variance function with a nonparametric variance fun...... hiện toàn bộ

Integrated likelihoods in parametric survival models for highly clustered censored data
Springer Science and Business Media LLC - Tập 22 Số 3 - Trang 382-404 - 2016
Cortese, Giuliana, Sartori, Nicola
In studies that involve censored time-to-event data, stratification is frequently encountered due to different reasons, such as stratified sampling or model adjustment due to violation of model assumptions. Often, the main interest is not in the clustering variables, and the cluster-related parameters are treated as nuisance. When inference is about a parameter of interest in presence of many nuis...... hiện toàn bộ
A general class of promotion time cure rate models with a new biological interpretation
Springer Science and Business Media LLC - Tập 29 - Trang 66-86 - 2022
Yolanda M. Gómez, Diego I. Gallardo, Marcelo Bourguignon, Eduardo Bertolli, Vinicius F. Calsavara
Over the last decades, the challenges in survival models have been changing considerably and full probabilistic modeling is crucial in many medical applications. Motivated from a new biological interpretation of cancer metastasis, we introduce a general method for obtaining more flexible cure rate models. The proposal model extended the promotion time cure rate model. Furthermore, it includes seve...... hiện toàn bộ
Distribution of the random future life expectancies in log-bilinear mortality projection models
Springer Science and Business Media LLC - Tập 13 - Trang 381-397 - 2007
Michel Denuit
Projected life tables are obtained from forecasting methods and account for future improvements in longevity. Since the future path of mortality is unknown, working with projected life tables makes the survival probabilities stochastic. The resulting demographic indicators in turn become random variables. This paper aims to study the distribution of period and cohort life expectancies derived from...... hiện toàn bộ
The competing risks Cox model with auxiliary case covariates under weaker missing-at-random cause of failure
Springer Science and Business Media LLC - Tập 24 - Trang 425-442 - 2017
Daniel Nevo, Reiko Nishihara, Shuji Ogino, Molin Wang
In the analysis of time-to-event data with multiple causes using a competing risks Cox model, often the cause of failure is unknown for some of the cases. The probability of a missing cause is typically assumed to be independent of the cause given the time of the event and covariates measured before the event occurred. In practice, however, the underlying missing-at-random assumption does not nece...... hiện toàn bộ
Nonparametric estimation in the illness-death model using prevalent data
Springer Science and Business Media LLC - Tập 23 - Trang 25-56 - 2016
Bella Vakulenko-Lagun, Micha Mandel, Yair Goldberg
We study nonparametric estimation of the illness-death model using left-truncated and right-censored data. The general aim is to estimate the multivariate distribution of a progressive multi-state process. Maximum likelihood estimation under censoring suffers from problems of uniqueness and consistency, so instead we review and extend methods that are based on inverse probability weighting. For un...... hiện toàn bộ
Frailty Models for Arbitrarily Censored and Truncated Data
Springer Science and Business Media LLC - Tập 10 Số 4 - Trang 369-388 - 2004
Huber-Carol, Catherine, Vonta, Ilia
In this paper, we propose a frailty model for statistical inference in the case where we are faced with arbitrarily censored and truncated data. Our results extend those of Alioum and Commenges (1996), who developed a method of fitting a proportional hazards model to data of this kind. We discuss the identifiability of the regression coefficients involved in the model which are the parameters of i...... hiện toàn bộ
