Bartlett corrections are derived for testing hypotheses about the autoregressive parameter . In the models with deterministic terms, the correction factor is asymmetric in and tends to infinity when approaches the stability boundary of + 1. Simulation results indicate that the Bartlett corrections are useful in controlling the size of the likelihood ratio statistic in small samples, although these corrections are not the ultimate panacea.
