Regression analysis of multiplicative hazards model with time-dependent coefficient for sparse longitudinal covariates
Zhuowei Sun, Hongyuan Cao
We study the multiplicative hazards model with intermittently observed longitudinal covariates and time-varying coefficients. For such models, the existing ad hoc approach, such as…

Regression analysis of longitudinal data with mixed synchronous and asynchronous longitudinal covariates
Zhuowei Sun, Hongyuan Cao, Li Chen +1
In linear models, omitting a covariate that is orthogonal to covariates in the model does not result in biased coefficient estimation. This in general does not hold for longitudina…

Regression analysis of mixed sparse synchronous and asynchronous longitudinal covariates with varying-coefficient models
Congmin Liu, Zhuowei Sun, Hongyuan Cao
We consider varying-coefficient models for mixed synchronous and asynchronous longitudinal covariates, where asynchronicity refers to the misalignment of longitudinal measurement t…
