T Li, T Li, Z Zhu, H Zhu - Journal of the American Statistical …, 2022 - Taylor & Francis
Many modern large-scale longitudinal neuroimaging studies, such as the Alzheimer's
Disease Neuroimaging Initiative (ADNI) study, have collected/are collecting asynchronous …

Kernel meets sieve: transformed hazards models with sparse longitudinal covariates

D Sun, Z Sun, X Zhao, H Cao - arXiv preprint arXiv:2308.15549, 2023 - arxiv.org
We study the transformed hazards model with intermittently observed time-dependent
covariates for the censored outcome. Existing work assumes the availability of the whole …

Asynchronous functional linear regression models for longitudinal data in reproducing kernel Hilbert space

T Li, H Zhu, T Li, H Zhu - Biometrics, 2023 - Wiley Online Library
Motivated by the analysis of longitudinal neuroimaging studies, we study the longitudinal
functional linear regression model under asynchronous data setting for modeling the …

Semiparametric model average prediction in panel data analysis

T Huang, J Li - Journal of Nonparametric Statistics, 2018 - Taylor & Francis
Forecasting in economic data analysis is dominated by linear prediction methods where the
predicted values are calculated from a fitted linear regression model. With multiple predictor …

Analysis of asynchronous longitudinal data with partially linear models

L Chen, H Cao - 2017 - projecteuclid.org
We study partially linear models for asynchronous longitudinal data to incorporate nonlinear
time trend effects. Local and global estimating equations are developed for estimating the …

Weighted regression analysis to correct for informative monitoring times and confounders in longitudinal studies

J Coulombe, EEM Moodie, RW Platt - Biometrics, 2021 - academic.oup.com
We address estimation of the marginal effect of a time-varying binary treatment on a
continuous longitudinal outcome in the context of observational studies using electronic …

Regression analysis of asynchronous longitudinal data with informative observation processes

D Sun, H Zhao, J Sun - Computational statistics & data analysis, 2021 - Elsevier
A great deal of literature has been established for regression analysis of longitudinal data
but most of the existing methods assume that covariates can be observed completely or at …

On functional processes with multiple discontinuities

J Li, Y Li, T Hsing - Journal of the Royal Statistical Society Series …, 2022 - academic.oup.com
We consider the problem of estimating multiple change points for a functional data process.
There are numerous examples in science and finance in which the process of interest may …

Regression analysis of longitudinal data with mixed synchronous and asynchronous longitudinal covariates

Z Sun, H Cao, L Chen, JP Fine - Journal of Statistical Planning and …, 2024 - Elsevier
In linear models, omitting a covariate that is orthogonal to covariates in the model does not
result in biased coefficient estimation. This generally does not hold for longitudinal data …

Regression analysis of mixed sparse synchronous and asynchronous longitudinal covariates with varying-coefficient models

C Liu, Z Sun, H Cao - Electronic Journal of Statistics, 2023 - projecteuclid.org
We consider varying-coefficient models for mixed synchronous and asynchronous
longitudinal covariates, where asynchronicity refers to the misalignment of longitudinal …
