title: 'sdf.test: Nonparametric Two Sample Test for Equality of Spectral Densities'
version: 0.0.1.0
doi: 10.32614/CRAN.package.sdf.test
abstract: 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.
