Improved Virtual Gyroscope Technology Based on the ARMA Model [PDF]

open access: yesMicromachines, 2018
In view of the large output noise and low precision of the Micro-electro-mechanical Systems (MEMS) gyroscope, the virtual gyroscope technology was used to fuse the data of the MEMS gyroscope to improve its output precision.

ARMA Model for Tracking Accelerated Corrosion Damage in a Steel Beam [PDF]

open access: yesSensors
This paper proposes an enhanced vibration-based damage detection index leveraging autoregressive moving average (ARMA) time-series modeling. The method relies on the fact that material deterioration alters the vibration features of the structure.

Sea Spectral Estimation Using ARMA Models [PDF]

open access: yesSensors, 2021
This paper deals with the spectral estimation of sea wave elevation time series by means of ARMA models. To start, the procedure to estimate the ARMA coefficients, based on the use of the Prony’s method applied to the auto-covariance series, is presented.

Moments of the ARMA–EGARCH model [PDF]

open access: yesThe Econometrics Journal, 2003
Summary: This paper considers the moment structure of the general ARMA-EGARCH model. In particular, we derive the autocorrelation function of any positive integer power of the squared errors. In addition, we obtain the autocorrelations of the squares of the observed process and cross correlations between the levels and the squares of the observed ...

Bayesian analysis of ARMA models [PDF]

open access: yes, 2000
Root cancellation in Auto Regressive Moving Average (ARMA) models leads tolocal non-identification of parameters. When we use diffuse or normal priorson the parameters of the ARMA model, posteriors in Bayesian analyzes show ana posteriori favor for this local non-identification. We show that the priorand posterior of the parameters of an ARMA model are

Hierarchical Bayesian Choice of Laplacian ARMA Models Based on Reversible Jump MCMC Computation

open access: yesInternational Journal of Computational Intelligence Systems, 2020
An autoregressive moving average (ARMA) is a time series model that is applied in everyday life for pattern recognition and forecasting. The ARMA model contains a noise which is assumed to have a specific distribution.
