      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 ...

      Empirical bayes approach to wavelet regression using ε-contaminated priors 

      Angelini, Claudia; Sapatinas, Theofanis (2004)
      We consider an empirical Bayes approach to standard nonparametric regression estimation using a nonlinear wavelet methodology. Instead of specifying a single prior distribution on the parameter space of wavelet coefficients, ...

      Wavelet estimators in nonparametric regression: A comparative simulation study 

      Antoniadis, Anestis; Bigot, J.; Sapatinas, Theofanis (2001)
      Wavelet analysis has been found to be a powerful tool for the nonparametric estimation of spatially-variable objects. We discuss in detail wavelet methods in nonparametric regression, where the data are modelled as ...
