. "FUNCTIONAL REGRESSION AND PRINCIPAL COMPONENTS ANALYSIS FOR SPARSE
LONGITUDINAL DATA"

Prof. Jane-Ling Wang
Dept. of Statistics, University of California at Davies 

RESUMEN
We porpose a nonparametric method to perform functional regression and
principal components analysis for sparce longitudinal data that consist of
noisy measurements with underlying smooth random trajectories for each
subject in a sample. The number of repeated measurement available per
subject is typically small, and their spacing is irregular. Our method
includes determination of the most appropiate function base from the data
and the associated coefficients of the basis functions for each individual.
The proposed method easily handles situations where for most subjects not
more than two measurements are available. It is also suitable for functional
regression where both the predictor and response are functions of a
covariate such as time. Asymptotic properties are investigated under mild
conditions, using tools from functional analysis. We ilustrate the methods
withba simulations study, longitudinal CD4 data in AIDS patients and a
functional regression analysis of the dynamic relationship of immunoproteins
albumin and CRP.n
