Abstract:
    Longitudinal data can be viewed as a type of functional
data.  The functional viewpoint is not typical for most 
analysts of longitudinal data, but provides a route for
powerful new insights.  The potential of this approach is
demonstrated though an analysis of periodicities in a micro
array gene expression data set.
