Multivariate, Locally Stationary Wavelet Process Estimation
Description
The mvLSW package provides an implementation of the multivariate locally stationary time series modelling approach proposed by Park, Eckley and Ombao (2014).
The approach extends the locally stationary wavelet time series work of
Nason, von Sachs and Kroisandt (2000) to a multivariate setting, introducing
wavelet-based measures of local coherence and local partial coherence. The
package implements the estimation scheme by Park et al. (2014) for such
processes. Note that mvLSW should be used in conjunction with the
wavethresh package developed by Nason (2016).
