DESCRIPTION:Many scientific areas are faced with the challenge
of extracting information from large\, complex\,
and highly structured data sets. A great deal of m
odern statistical work focuses on developing tools
for handling such data. In this work we presents
a new subfield of functional data analysis\, FDA\,
which we call Manifold Data Analysis\, or MDA. MD
A is concerned with the statistical analysis of sa
mples where one or more variables measured on each
unit is a manifold\, thus resulting in as many ma
nifolds as we have units. We propose a framework t
hat converts manifolds into functional objects\, a
n efficient 2-step functional principal component
method\, and a manifold-on-scalar regression model
. This work is motivated by an anthropological ap
plication involving 3D facial imaging data\, which
is discussed extensively throughout. The propose
d framework is used to understand how individual c
haracteristics\, such as age and genetic ancestry\
, influence the shape of the human face.
