在高斯自回归模型中检验单位根时,不满足Bartlett校正的通常条件。然而,通过扩展似然比统计量的矩,可以表明Bartlett校正改善了渐近分布近似。
The usual conditions for a Bartlett correction are not fulfilled when testing for a unit root in a Gaussian autoregressive model. However, by expanding the moments of the likelihood ratio statistic it can be shown that the Bartlett correction improves the asymptotic distribution approximation.
