Abstract: Suppose that is the least squares estimator constructed from observations of an unknown matrix in an autoregressive process . Under the assumption that the sequence is a martingale difference, not necessarily stationary and ergodic, we find the limit distribution as of the statistic by using methods of stochastic analysis. This limit distribution may be different from the normal distribution.
