Asymptotic simultaneous confidence bands for vector autoregressive spectra
向量自回归谱的渐近同时置信带
Asymptotic simultaneous confidence bands for all ω in [0, 0.5] are obtained for each scalar function in a spectral density matrix, as well as for the logarithm of the autospectra, the squared coherence and the phase spectra. The bands are illustrated using a simulation study and surface elevation data.
