A new statistical test based on the wavelet cross-spectrum to detect time-frequency dependence between non-stationary signals: Application to the analysis of cortico-muscular interactions
The study of the correlations that may exist between neurophysiological signals is at the heart of modern techniques for data analysis in neuroscience. Wavelet coherence is a popular method to construct a time-frequency ...
Fitting Distributions With The Polyhazard Model With Dependence
(TAYLOR & FRANCIS INCPHILADELPHIA, 2015)
Disability, caregiver's dependency and patterns of access to rehabilitation care: results from a national representative study in Peru
(Taylor & Francis, 2015)
PURPOSE: To determine the prevalence of disability in Peru, explore dependency on caregiver's assistance and assess access to rehabilitation care. METHOD: Data from Disability National Survey (ENEDIS), including urban and ...
Separation of particles in time-dependent focusing billiards
(Elsevier B.V., 2010-12-01)
We consider a family of stadium-like billiards with time-dependent boundaries. Two different cases of time dependence are studied: (i) the fixed boundary approximation and (ii) the exact model which takes into account the ...
A time dependent Bayesian nonparametric model for air quality analysis
Air quality monitoring is based on pollutants concentration levels, typically recorded in metropolitan areas. These exhibit spatial and temporal dependence as well as seasonality trends, and their analysis demands flexible ...
Copula-based measures of dependence structure in assets returns
Copula modeling has become an increasingly popular tool in finance to model assets returns dependency. In essence, copulas enable us to extract the dependence structure from the joint distribution function of a set of ...
