Representing functional data in reproducing Kernel Hilbert Spaces with applications to clustering and classification

González, Javier; Muñoz, Alberto - Departamento de Estadistica, Universidad Carlos III de … - 2010

Functional data are difficult to manage for many traditional statistical techniques given their very high (or … intrinsically infinite) dimensionality. The reason is that functional data are essentially functions and most algorithms are … representations of functional data. The key idea is to consider each functional curve as a point in a general function space and then …

Forecasting age-related changes in breast cancer mortality among white and black US women: A functional approach

Yasmeen, Farah; Hyndman, Rob J; Erbas, Bircan - Department of Econometrics and Business Statistics, … - 2010

The disparity in breast cancer mortality rates among white and black US women is widening with higher mortality rates among black women. We apply functional time series models on age-specific breast cancer mortality rates for each group of women, and forecast their mortality curves using...

Testing for a Constant Mean Function using Functional Regression

Cho, Jin Seo; Huang, Meng; White, Halbert - Institute of Economic Research, Korea University - 2009

In this paper, we study functional regression and its properties in testing the hypothesis of a constant zero mean function or an unknown constant non-zero mean function. As we show, the associated Wald test statistics have standard chi-square limiting null distributions, standard non-central...
