Precision of yule-walker methods for the arma spectral model
(2004-12-01)
In this work a new method is proposed of separated estimation for the ARMA spectral model based on the modified Yule-Walker equations and on the least squares method. The proposal of the new method consists of performing ...
A unified approach to the study of sums, products, time-aggregation and other functions of ARMA processes
(John Wiley & Sons Ltd, 1984)
Conditions under which sums, products and time-aggregation of ARMA processes follow ARMA models are derived from a single theorem. This characterizes these processes in terms of difference equations satisfied by their ...

Data-driven identification of rotating machines using ARMA deterministic parameter evolution in the angle/time domain
(2020-09-01)
The functional-series angle-/time-varying autoregressive moving-average (AT-FS-ARMA) model was used to model and analyze vibration-based signals from internal combustion engines. This approach is derived from the formulation ...
Modelo Weibull autorregressivo de médias móveis: um novo modelo para aplicações em séries de vazão e velocidade do vento
(Universidade Federal de Santa MariaBrasilEngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia CivilCentro de Tecnologia, 2022-02-23)
Hydroclimatic processes, such as streamflow and wind speed, have a probabilistic nature
since they suffer interference from an infinite number of random factors. Most
of the time series within the natural sciences also ...
