Bayesian Wavelet Shrinkage of the Haar-Fisz Transformed Wavelet Periodogram.
It is increasingly being realised that many real world time series are not stationary and exhibit evolving second-order autocovariance or spectral structure. This article introduces a Bayesian approach for modelling the evolving wavelet spectrum of a locally stationary wavelet time series. Our new m...
