Clustering of multivariate time-series data [PDF]

open access: yesProceedings of the 2002 American Control Conference (IEEE Cat. No.CH37301), 2002
A new methodology for clustering multivariate time-series data is proposed. The methodology is based on calculation of the degree of similarity between multivariate time-series datasets using two similarity factors. One similarity factor is based on principal component analysis and the angles between the principal component subspaces while the other is

Nonparametric frequency domain analysis of nonstationary multivariate time series [PDF]

open access: yes, 2002
We analyse the properties of nonparametric spectral estimates when applied to long memory and trending nonstationary multiple time series. We show that they estimate consistently a generalized or pseudo-spectral density matrix at frequencies both close ...

Inferring causal relations from multivariate time series : a fast method for large-scale gene expression data [PDF]

open access: yes, 2009
Various multivariate time series analysis techniques have been developed with the aim of inferring causal relations between time series. Previously, these techniques have proved their effectiveness on economic and neurophysiological data, which normally ...

Network structure of multivariate time series [PDF]

open access: yesScientific Reports, 2015
AbstractOur understanding of a variety of phenomena in physics, biology and economics crucially depends on the analysis of multivariate time series. While a wide range tools and techniques for time series analysis already exist, the increasing availability of massive data structures calls for new approaches for multidimensional signal processing.

Goodness-of-Fit Tests for Copulas of Multivariate Time Series

open access: yesEconometrics, 2017
In this paper, we study the asymptotic behavior of the sequential empirical process and the sequential empirical copula process, both constructed from residuals of multivariate stochastic volatility models. Applications for the detection of structural

Online Clustering of Multivariate Time-series [PDF]

open access: yesProceedings of the 2016 SIAM International Conference on Data Mining, 2016
Copyright © by SIAM. The intrinsic nature of streaming data requires algorithms that are capable of fast data analysis to extract knowledge. Most current unsupervised data analysis techniques rely on the implementation of known batch techniques over a sliding window, which can hinder their utility for the analysis of evolving structure in applications ...

Modelling multiple time series via common factors [PDF]

open access: yes, 2008
We propose a new method for estimating common factors of multiple time series. One distinctive feature of the new approach is that it is applicable to some nonstationary time series. The unobservable, nonstationary factors are identified by expanding the
