Asymptotic Null Distributions of Stationarity and Nonstationarity Tests Under Local-to-finite Variance Errors

Abstract: The purpose of this paper is to investigate the asymptotic null distribution of stationarity and nonstationarity tests when the distribution of the error term belongs to the normal domain of attraction of a stable law in any finite sample but the error term is an i.i.d. process with finite variance as T ↑ ∞. This local-to-finite variance setup is helpful to highlight the behavior of test statistics under the null hypothesis in the borderline or near borderline cases between finite and infinite variance and to … Show more

“…Amsler and Schmidt (1999) derived the asymptotic distribution of the KPSS statistic with no lags ( = 0), which is exactly as in Equation (5) except that G * α,c (r) replaces U * α (r) in the numerator of the expression for the asymptotic distribution. That is, Cappuccio and Lubian (2007) also derived these results for the KPSS and MR/S tests, as well as the LM test and several other tests. We will therefore omit the proofs here.…”

“…The parameterization was first suggested and the proofs of the asymptotic results given in the current article were presented by Amsler and Schmidt (1999), but that paper was never published. These results were used, and some of them were proved again, by Callegari, Cappuccio, and Lubian (2003) and Cappuccio and Lubian (2007). Those articles quoted Amsler and Schmidt (1999) but gave a somewhat self-contained presentation of the results.…”

“…This local-to-finite variance setup is helpful to highlight the behavior of test statistic under the null hypothesis in the borderline or near borderline cases between finite variance, and assess the robustness of our test statistic to small departure from the standard finite variance context. One refer Callegari et al (2003), Cappuccio and Lubian (2007) for more detailed discussions about this sequence. (2) is generated by (9), and Assumption 2.2 holds, then the null distribution of (6) is given bỹ (2) is generated by (9), then under Assumption 2.2 the result of Theorem 3.3 is still hold.…”
