Portmanteau test and simultaneous inference for serial covariances
2014
Statistica sinica
The paper presents a systematic theory for asymptotic inferences based on autocovariances of stationary processes. We consider nonparametric tests for serial correlations using the maximum (or L ∞ ) and the quadratic (or L 2 ) deviations of sample autocovariances. For these cases, with proper centering and rescaling, the asymptotic distributions of the deviations are Gumbel and Gaussian, respectively. To establish such an asymptotic theory, as byproducts, we develop a normal comparison
