We consider a multivariate linear model with autocorrelated errors. The mean vector of the process is assumed to be linear in the time-trend parameter β and the within-group variation parameter γ. The least-squares estimators of β and γ, and the related estimators of the autoregressive parameter θ and the error covariance matrix Σ are derived and their asymptotic distributions are obtained. Large sample tests of H1:γ=0 and H2:β=0are derived and the limit distributions of the restricted least-squares estimators β̂H1 and γ̂H2 are obtained under H1 and H2, respectively.
