    • Denoising Non-stationary Signals by Dynamic Multivariate Complex Wavelet Thresholding 

      Raath, Kim; Ensor, Katherine B.; Scott, David W.; Crivello, Alena (2020)
      Over the past few years, we have seen an increased need for analyzing the dynamically changing behaviors of economic and financial time series.
