Estimation of parameters of autoregressive models with fractional differences in the presence of additive noise

open access: yesВестник Самарского университета: Естественнонаучная серия, 2023
For modeling in time series, models with fractional differences are widely used. The best known model is the ARFIMA (autoregressive fractionally integrated moving average) model.

Modification of ARL for detecting changes on the double EWMA chart in time series data with the autoregressive model

open access: yesConnection Science, 2023
This research aims to derive the average run length (ARL) evaluation of the double exponentially weighted moving average (double EWMA) control chart for observation data that follows exponential white noise in a time series model with an autoregressive ...

Saturation in autoregressive models [PDF]

open access: yesNotas Económicas, 2006
In this paper, we extend the impulse saturation algorithm to a class of dynamic models. We show that the procedure is still correctly sized for stationary AR(1) processes, independently of the number of splits used for sample partitions. We derive theoretical power when there is an additive outlier in the data, and present simulation evidence showing ...

Tempered stable autoregressive models

open access: yesCommunications in Statistics - Theory and Methods, 2022
In this article, we introduce and study a one sided tempered stable first order autoregressive model called TAR(1). Under the assumption of stationarity of the model, the marginal probability density function of the error term is found. It is shown that the distribution of the error term is infinitely divisible.

Spatial Temporal Conditional Auto-Regressive Model: A New Autoregressive Matrix

open access: yesAustrian Journal of Statistics, 2016
In the study of geographical patterns of disease, multivariate areal data models proposed so far in the literature (Ma and Carlin, 2007; Carlin and Banerjee, 2003; Knorr-Held and Best, 2001) have allowed to handle several features of a phenomenon at the ...

Any-to-One Non-Parallel Voice Conversion System Using an Autoregressive Conversion Model and LPCNet Vocoder

open access: yesApplied Sciences, 2023
We present an any-to-one voice conversion (VC) system, using an autoregressive model and LPCNet vocoder, aimed at enhancing the converted speech in terms of naturalness, intelligibility, and speaker similarity.
