Asymptotic simultaneous confidence bands for all
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.
Key Words: Periodic autoregressive process; Simultaneous confidence bands; Spectral density matrix; Vector autoregressive process
