Efficient Estimation For The Joint Model of Survival and Longitudinal Data
Khandoker Akib Mohammad, Yuichi Hirose, Yuan Yao +1
In survival studies it is important to record the values of key longitudinal covariates until the occurrence of event of a subject. For this reason, it is essential to study the as…
Efficient Estimation For The Cox Proportional Hazards Cure Model
Khandoker Akib Mohammad, Yuichi Hirose, Budhi Surya +1
While analysing time-to-event data, it is possible that a certain fraction of subjects will never experience the event of interest and they are said to be cured. When this feature…
Statistical generalized derivative applied to the profile likelihood estimation in a mixture of semiparametric models
Yuichi Hirose, Ivy Liu
There is a difficulty in finding an estimate of variance of the profile likelihood estimator in the joint model of longitudinal and survival data. We solve the difficulty by introd…
On differentiability of implicitly defined function in semi-parametric profile likelihood estimation
Yuichi Hirose
In this paper, we study the differentiability of implicitly defined functions which we encounter in the profile likelihood estimation of parameters in semi-parametric models. Scott…
Reparametrization of the least favorable submodel in semi-parametric multisample models
Yuichi Hirose, Alan Lee
The method of estimation in Scott and Wild (Biometrika 84 (1997) 57--71 and J. Statist. Plann. Inference 96 (2001) 3--27) uses a reparametrization of the profile likelihood that of…
