Functional Data Analysis: From Basics to Current Topics of Interest

Hans-Georg Mueller and Jane-Ling Wang, University of California, Davis, USA.

With the advance of modern technology, more and more data are being recorded continuously during a time interval or intermittently at several discrete time points for many units or subjects. These are instances of "functional data". Functional Data Analysis (FDA) encompasses the statistical methodology for such data. Broadly interpreted, FDA deals with the analysis and theory of data that are in the form of functions, or can thought of as being generated by latent functions.

We provide an introduction into the most commonly used methods of FDA. These include Functional Principal Component Analysis (FPCA) and the related concept of modes of variation, which is based on simple statistical notions such as mean and covariance function of a random process that can be inferred from the data. FPCA is an important dimension reduction tool and in sparse data situations can be used to impute functional data that are sparsely observed.

Another core topic of FDA is functional regression, where one pairs functions or scalars as predictors with responses that are also functions or scalars. A classical model is functional linear regression, which can be implemented for combinations of vectors and functions in both predictors and responses. For the case where the predictors include functions, a difficult step that requires regularization is the inversion of a covariance operator, which is an ill-posed problem. Such an inverse problem is also related to some forms of functional correlation, which will be another core topic.

Beyond the linear modeling approaches, nonlinear methods have found increasing interest. These include polynomial and quadratic regression relations, dimension reduction methods such as additive, continuously additive and index models, and other nonlinear approaches. Such approaches are also useful for shape constrained functional data such as samples of densities.

Further topics of interest that may be covered are warping and manifold learning, the learning of time dynamics from observed realizations of the underlying stochastic process, multivariate and repeatedly observed functional data and stringing of high-dimensional data into functional data.

Bootstrap in separable Hilbert spaces with applications to functional data analysis

Gil Gonzalez-Rodriguez, University of Oviedo, Spain.

Hilbert spaces are frequently used in statistics as a framework to deal with general random elements, specially with functional-valued random variables. The scarcity of common parametric distribution models in this context makes it important to develop non-parametric techniques,and among them, bootstrap has already proved to be specially valuable.

The aim is to illustrate how to derive consistent bootstrap approaches in separable Hilbert spaces. Naive bootstrap, bootstrap with arbitrary sample size, wild bootstrap, and several weighted bootstrap methods, including, e.g., double bootstrap, and bootstrap generated by deterministic weights, with the particular case of delete$-h$ jackknife,will be obtained as examples within the considered framework. The main results concern the bootstrapped sample mean, however since many frequent statistics can be written in terms of means by considering suitable spaces, the applicability is notable. An illustration to show how to employ the approach in the context of a functional regression problem is discussed.
