There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

TITLE: Functional Regression Models
SPEAKER: Hans-Georg Mueller
ABSTRACT:
Functional regression has emerged as a useful approach for the analysis of
complex data that combine functional or longitudinal predictors with scalar
or functional responses. A major emphasis has been the functional linear
regression model, which allows to implement dimension reduction in a simple
and straightforward way but may be too restrictive. We will discuss flexible
extensions of this model. These include functional quadratic, polynomial and
additive models. Of special interest is differentiation with respect to a
functional argument, for which additive models are particularly well suited.
Another extension are local models, where the focus is on the dependency of
a Gaussian process or its derivatives at a given time on the value of a
predictor process at the same or a different time. The methods will be
illustrated with densely as well as sparsely sampled functional data. This
talk is based on joint work with Wenjing Yang and Fang Yao.
