Dynamic Modeling of Conditional Quantile Trajectories, With Application to Longitudinal Snippet Data
条件分位数轨迹的动态建模及其纵向短片段数据应用
Longitudinal data are often plagued with sparsity of time points where measurements are available. The functional data analysis perspective has been shown to provide an effective and flexible approach to address this problem for the case where measurements are sparse but their times are randomly distributed over an interval. Here, we focus on a different scenario where available data can be characterized as snippets, which are very short stretches of longitudinal…
