Wavelet analysis for non-stationary, nonlinear time series
Methods for detecting and quantifying nonlinearities in nonstationary time series are introduced and developed. In particular, higher-order wavelet analysis was applied to an ideal time series and the quasi-biennial oscillation (QBO) time series. Multiple-testing problems inherent in wavelet analysis were addressed by controlling the false discovery rate. A new local autobicoherence spectrum fa...
متن کاملAnalysis of Non-Stationary Time Series using Wavelet Decomposition
Abstract: The increased computational speed and developments in the area of algorithms have created the possibility for efficiently identifying a well-fitting time series model for the given nonstationary-nonlinear time series and use it for prediction. In this paper a new method is used for analyzing a given nonstationary-nonlinear time series. Based on the Multiresolution Analysis (MRA) and n...
متن کاملA Fuzzy-Wavelet Method for Analyzing Non-Stationary Time Series
Fuzzy rule based systems are increasingly being used to deal with time series processes that may lack stochastic stability due to non-stationarity, multiscaling and persistent autocorrelations. Wavelet filtering can be used to deal with such phenomenon. A method for creating a fuzzy-rule base from a time series, where the first difference (returns) of the preprocessed series is used, and high f...
متن کاملUsing Wavelets and Splines to Forecast Non-Stationary Time Series
This paper deals with a short term forecasting non-stationary time series using wavelets and splines. Wavelets can decompose the series as the sum of two low and high frequency components. Aminghafari and Poggi (2007) proposed to predict high frequency component by wavelets and extrapolate low frequency component by local polynomial fitting. We propose to forecast non-stationary process u...
متن کاملForecasting non-stationary time series by wavelet process modelling
Many time series in the applied sciences display a time-varying second order structure. In this article, we address the problem of how to forecast these non-stationary time series by means of non-decimated wavelets. We first consider a model in which only the variance evolves with time. We define a predictor for this model and show an application to the Dow Jones index. Then, we generalise the ...
