Abstract:
This paper deals with the distributions evolving from the likelihood‐ratio test for the factor 1 −Bn in the lag polynomial Φ(B) under the basic assumption that the data series is generated by the autoregressive model Φ(B)Xt = εt where {εt} denotes Gaussian white noise. A characterization of the statistic and its asymptotic properties is given. Asymptotic and finite‐sample significance points are tabulated. The test procedure is illustrated by an economics example.
