Abstract: Abstract Consider longitudinal data $$x_{ij},$$ x ij , with $$i=1,...,n$$ i = 1 , . . . , n and $$j=1,...,p,$$ j = 1 , . . . , p , where $$x_{ij}$$ x ij is the observation of the smooth random function $$X_{i}\left( .\right) $$ X i . at time $$t_{j}.$$ t j . The goal of this paper is to develop a parsimonious representation of the data by a linear combination of a set of $$q
