Detecting trends in time series of functional data: a study of antarctic climate change
(Wiley, 2014-12)
The Spanish Antarctic Station Juan Carlos I has been registering surface air temperatures with the frequency of one reading per ten minutes since the austral summer 1987-88. Although this data set contains valuable information ...
Functional data analysis for Brazilian term structure of interest rate curves
(Lociedade Brasileira de Finanças, 2022)
A bivariate generalized exponential distribution derived from copula functions in the presence of censored data and covariates
(2015-01-01)
In this paper, we introduce a Bayesian analysis for a bivariate generalized exponential distribution in the presence of censored data and covariates derived from Copula functions. The generalized exponential distribution ...
Some features of the acceleration impulse response function
(2021-01-01)
Impulse response functions (IRFs) and frequency response functions (FRFs) are fundamental quantities that describe the dynamic behaviour of a linear vibrating system in the time and frequency domains respectively. The ...
Density kernel depth for outlier detection in functional data
(Springer NatureInternational Journal of Data Science and Analytics, 2023)
In this paper, we propose a novel approach to address the problem of functional outlier detection. Our method leverages a
low-dimensional and stable representation of functions using Reproducing Kernel Hilbert Spaces ...
Influence function of projection-pursuit principal components for functional data
(Elsevier Inc, 2015-01)
In the finite-dimensional setting, Li and Chen (1985) proposed a method for principal components analysis using projection-pursuit techniques. This procedure was generalized to the functional setting by Bali et al. (2011), ...
A nonparametric bayesian approach for modeling and comparison of functional data
(Universidade Federal de São CarlosUFSCarPrograma Interinstitucional de Pós-Graduação em Estatística - PIPGEsCâmpus São Carlos, 2022-09-02)
The current advances of technology provides, among other things, several ways of collecting
data, which enlarges the possibility of studying new phenomena. Researches focused on studying
the functional relation between ...
A Hierarchical Model for Aggregated Functional Data
(Amer Statistical AssocAlexandriaEUA, 2013)
O controle de autoridade no domínio bibliográfico: os catálogos digitais1
(2017-01-01)
In this paper we use a literature review to analyze authority control in digital catalogs. In order to do that, we start with a brief introduction to authority control, we contextualize library automation and the rising ...
