Abstract:
|
Assessing the associations between high-dimensional longitudinal biomarkers and longitudinal outcomes is often of scientific interest but often faces many challenges in real biomedical studies. The data complications include the high-dimensionality, skewness, incompleteness, and constraint of biomarkers along with the longitudinal nature of both biomarkers and outcomes. In this work, we develop a flexible generalization of the recently proposed globally adaptive quantile regression framework to address such complex data scenarios. We develop efficient algorithm to solve the proposed estimation and inference procedures. The proposals are evaluated via extensive simulation studies and an application to a prospective observational dataset.
