Fractional lower-order covariance-based measures for cyclostationary time series with heavy-tailed distributions: application to dependence testing and model order identification
Wojciech Żuławiński, Agnieszka Wyłomańska
This article introduces new methods for the analysis of cyclostationary time series with infinite variance. Traditional cyclostationary analysis, based on periodically correlated (…
Applications of robust statistics for cyclostationarity detection in non-Gaussian signals for local damage detection in bearings
Wojciech Żuławiński, Jérôme Antoni, Radosław Zimroz +1
Signals with periodic characteristics are ubiquitous in real-world applications. One of these areas is condition monitoring, where the vibration signals from rotating machines natu…
The modified Yule-Walker method for multidimensional infinite-variance periodic autoregressive model of order 1
Prashant Giri, Aleksandra Grzesiek, Wojciech Żuławiński +2
The time series with periodic behavior, such as the periodic autoregressive (PAR) models belonging to the class of the periodically correlated processes, are present in various rea…
Identification and validation of periodic autoregressive model with additive noise: finite-variance case
Wojciech Żuławiński, Aleksandra Grzesiek, Radosław Zimroz +1
In this paper, we address the problem of modeling data with periodic autoregressive (PAR) time series and additive noise. In most cases, the data are processed assuming a noise-fre…
