Empirical Bayes approach to block wavelet function estimation
(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
(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
(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 ...
