This function provides an empirical estimate of the wavelet cross-covariance given multiple processes.

wccv_local(Xt)

Arguments

Xt

A matrix of dimension T by p, where T is the length of the time series and p is the number of processes.

Value

A list with the following structure:

  • wccv: A matrix of the estimated wavelet cross-covariance.

  • wccv.cov: A matrix of the estimated covariance matrix of the estimated wavelet cross-covariance.

  • ci_low: A matrix of the lower bound of the confidence interval of the estimated wavelet cross-covariance.

  • ci_high: A matrix of the upper bound of the confidence interval of the estimated wavelet cross-covariance.
