A wavelet Whittle estimator of the memory parameter of a nonstationary Gaussian time series
E Moulines, F Roueff, MS Taqqu - 2008 - projecteuclid.org
We consider a time series X={X k, k∈ ℤ} with memory parameter d 0∈ ℝ. This time series is
either stationary or can be made stationary after differencing a finite number of times. We …
