On the Identification of ARMA Graphical Models
The paper considers the problem to estimate a graphical model corresponding to an autoregressive moving-average (ARMA) Gaussian stochastic process. We propose a new maximum entropy covariance and cepstral extension problem and we show that the problem admits an approximate solution which represents an ARMA graphical model whose topology is determined ...

Simplified Machine Diagnosis Techniques Using 3rd order ARMA Model of Absolute Deterioration Factor
In order to diagnose machines accurately, the Kurtosis and Bicoherence methods were utilized. Calculating system parameter distance was also utilized to apply time series data to Autoregressive (AR) model or Autoregressive Moving Average (ARMA) model. In

MODEL SELECTION CRITERIA AND QUADRATIC DISCRIMINATION IN ARMA AND SETAR TIME SERIES MODELS [PDF]
We show that analyzing model selection in ARMA time series models as a quadratic discrimination problem provides a unifying approach for deriving model selection criteria.

Asymptotic Theory for a Vector ARMA-GARCH Model, [PDF]
This paper investigates the asymptotic theory for a vector ARMA-GARCH model. The conditions for the strict stationarity, ergodicity, and the higherorder moments of the model are established.

Another Look at the (Ir)Relevance of Long‐Run Risks for Equity Risk Premia
Abstract I investigate the empirical asset pricing implications of a three‐factor macro model that extends the baseline consumption model Consumption Capital Asset Pricing Model (CCAPM) by adding the innovations in expected long‐run consumption growth (consumption growth news) and expected long‐run consumption variance (variance news) as risk factors ...
