Multivariate time series data often have a very high dimensionality. Classifying such high dimensional data poses a challenge because a vast number of features can be extracted. Furthermore, the meaning of the normally intuitive term "similar to" needs to be precisely defined. Representing the time...
Copula-Based Multivariate Time Series Models 来自 igi-global.com 喜欢 0 阅读量: 44 作者: I Mihaylova 摘要: Top Chapter Preview Top Introduction It has been more than fifty years since Abe Sklar introduced the concept "copula", meaning "a connection", in the context of probabilistic metric ...
Thus, the apparent chaotic behavior of a time-series can mean the manifestation of a dynamic system. Often, these phenomena are recurrent, meaning that certain regions of their available state space are frequently visited along of time. For this reason, the use of recurrence plots (RPs) and ...
A growing number of algorithms have been proposed to map a scalar time series into ordinal partition transition networks. However, most observable phenomena in the empirical sciences are of a multivariate nature. We construct ordinal partition transition networks for multivariate time series. This approa...

We simulated a complex noise scenario by replacing additive noise with multiplicative noise, meaning that the amount of noise depends on the variable level (here species abundance). The multiplicative noise scenario hardly affects the autocorrelation based indicators in the 4D model, but it has a de...
