Bayesian Sample Size Determination for Joint Modeling of Longitudinal Measurements and Survival Data
A longitudinal study refers to collection of a response variable and possibly some explanatory variables at multiple follow-up times. In many clinical studies with longitudinal measurements, the response variable, for each patient is collected as long as an event of interest, which considered as clinical end point, occurs. Joint modeling of continuous longitudinal measurements and survival time...
متن کاملJoint modeling of longitudinal categorical data and survival data
In many biomedical studies, it is of interest to study the covariate effect on both longitudinal categorical outcomes and survival outcomes. For example, in cancer research, it is of interest to study the treatment effect on both quality of life which is a categorical outcome measured longitudinally and survival time. In this talk, we will discuss such joint models. Random effects are introduce...
متن کاملJoint modeling of survival and longitudinal data: likelihood approach revisited.
The maximum likelihood approach to jointly model the survival time and its longitudinal covariates has been successful to model both processes in longitudinal studies. Random effects in the longitudinal process are often used to model the survival times through a proportional hazards model, and this invokes an EM algorithm to search for the maximum likelihood estimates (MLEs). Several intriguin...
متن کاملJoint Modeling of Longitudinal and Cure-survival Data.
This article presents semiparametric joint models to analyze longitudinal measurements and survival data with a cure fraction. We consider a broad class of transformations for the cure-survival model, which includes the popular proportional hazards structure and the proportional odds structure as special cases. We propose to estimate all the parameters using the nonparametric maximum likelihood...
متن کاملlongitudinal assessment of serum creatinine levels on graft survival after renal transplantation: joint modeling approach
conclusions the major finding of this study is that one unit increase in serum creatinine level suggests an increased risk of graft failure of up to four times. patients and methods this study was carried out at the department of nephrology, baqiyatallah hospital, baqiyatallah university, tehran, iran, between april 2005 and december 2008. during that time period, 461 patients who had undergone...
