We use saddlepoint approximation to derive credible intervals for Bayesian wavelet regression estimates.Simulations show that the resulting intervals perform better than the best existing method.
Key Words: Bayesian thresholding; Discrete wavelet transform; Mixture distribution; Nonparameter regression; Saddlepoint approximation
