DOI: 10.1002/sim.9433
Abstract: Time‐varying biomarkers reflect important information on disease progression over time. Dynamic prediction for event occurrence on a real‐time basis, utilizing time‐varying information, is crucial in making accurate clinical decisions. Functional principal component analysis (FPCA) has… read more here.

DOI: 10.1007/s11222-016-9708-4
Abstract: This paper focuses on the analysis of spatially correlated functional data. We propose a parametric model for spatial correlation and the between-curve correlation is modeled by correlating functional principal component scores of the functional data.… read more here.

DOI: 10.1080/03610926.2019.1649429
Abstract: Abstract In this short paper, we consider the convergence rate of functional linear regression in prediction loss. For upper bound we consider estimation of the slope function based on functional principal component analysis. Lower bound… read more here.

DOI: 10.1080/14763141.2017.1384050
Abstract: Abstract Sporting performance is often investigated through graphical observation of key technical variables that are representative of whole movements. The presence of differences between athletes in such variables has led to terms such as movement… read more here.
