Statistical inference in vector autoregressions with possibly integrated processes
Hiro Y. Toda,Taku Yamamoto +1 more
TL;DR: In this paper, the authors show how to estimate VAR's formulated in levels and test general restrictions on the parameter matrices even if the processes may be integrated or cointegrated of an arbitrary order.
Journal ArticleDOI
Asymptotic Mean Square Prediction Error for an Autoregressive Model with Estimated Coefficients
TL;DR: In this paper, a manageable expression for the asymptotic mean square error of predicting more than one step ahead from an estimated autoregressive model is derived, which relies on a useful lemma on matrix differentiation.
Journal ArticleDOI
Properties of Predictors in Misspecified Autoregressive Time Series Models
Naoto Kunitomo,Taku Yamamoto +1 more
TL;DR: In this article, the effects of misspecification in stationary linear time series models when they fit a pth-order autoregressive model were investigated and the formulas of bias and mean squared error (MSE) of the least squares estimator and the hth period ahead prediction MSE in the time domain.
Journal ArticleDOI
Predictions of multivariate autoregressive-moving average models
TL;DR: In this article, a simple formula for multiperiod predictions of multivariate autoregressive-moving average models is derived, explicitly given as a function of suitably defined parameter matrices and an observation vector, and includes simpler models as its special cases.
Journal ArticleDOI
Modified lag augmented vector autoregressions
Eiji Kurozumi,Taku Yamamoto +1 more
TL;DR: In this paper, the authors proposed an inference procedure for a possibly integrated vector autoregression (VAR) model using the jackknife method to exclude the quasi-asymptotic bias associated with the term Op(T-1) using the LS-VAR estimator.
