WebJun 15, 2014 · McLeod [10, Theorem 1] has shown that is approximately normal with mean and , where , is the identity matrix, and is the Fisher information matrix. The superscript stands for transposition of matrix. We noticed that approximation of by , especially when is small, is a source of bias in approximating the asymptotic distribution of portmanteau tests.

WebJul 1, 2024 · Theorem 2.1 and (2.6) indicate that, when some parameters are on the boundary, the portmanteau test statistic will have non-standard asymptotic distribution. Since the limiting distribution of Q T depends on Λ , directly using critical values of χ M 2 distribution could lead to misleading statistical decisions and we may have to calculate … Web3) lim sup n!1 n(F) (F) for all closed F S. 4) lim inf n!1 n(G) (G) for all open G S. 5) lim n!1 n(A) = (A) for all -boundaryless A2S, i.e. A2Swith (A nA ) = 0, where A is the closure and A the interior of A. If one thinks of n; as the distributions of S-valued random variables X n;X, one often uses instead of weak convergence of n to the terminology that the X map of denali area
