      A comparative simulation study of wavelet shrinkage estimators for Poisson counts 

      Besbeas, P.; De Feis, I.; Sapatinas, Theofanis (2004)
      Using computer simulations, the finite sample performance of a number of classical and Bayesian wavelet shrinkage estimators for Poisson counts is examined. For the purpose of comparison, a variety of intensity functions, ...

      Empirical Bayes approach to block wavelet function estimation 

      Abramovich, F.; Besbeas, P.; Sapatinas, Theofanis (2002)
      Wavelet methods have demonstrated considerable success in function estimation through term-by-term thresholding of the empirical wavelet coefficients. However, it has been shown that grouping the empirical wavelet coefficients ...
