Keywords: Optimal estimation; quantile regression; functional data; reproducing kernel Hilbert space; ADNI; ADMM
Abstract:

Functional and nonfunctional data are often encountered simultaneously in modern experiments for example the clinical trial as well in economics. However it's difficult to consider both data at the same time. We considered functional partial linear quantile regression in this paper where both infinite dimension functional as well as finite dimension slope parameters are included. We study the theoretical properties under a reproducing kernel Hilbert space framework, which was being proved to be very flexible and powerful. Under this framework, we also developed an ADMM algorithm, which is very easy to implement in practical applications. Simulation studies and real data studies from ADNI are performed to validate our propose methodology and practical applications respectively.
