%description
Nonparametric method for testing the equality of the spectral densities of
two time series of possibly different lengths. The time series are
preprocessed with the discrete cosine transform and the variance
stabilising transform to obtain an approximate Gaussian regression setting
for the log-spectral density function. The test statistic is based on the
squared L2 norm of the difference between the estimated log-spectral
densities. The test returns the result, the statistic value, and the
p-value. It also provides the estimated empirical quantile and null
distribution under the hypothesis of equal spectral densities. An example
using EEG data is included. For details see Nadin, Krivobokova, Enikeeva
(2026), <doi:10.48550/arXiv.2602.10774>.
