Johnstone and Silverman (1997) described a level-dependent thresholding
method for extracting signals from correlated noise. The thresholds were chosen
to minimize a data based unbiased risk criteri...
Minimax Estimation via Wavelet Shrinkage

We attempt to recover a function of unknown smoothness from noisy, sampled
data. We introduce a procedure, SureShrink, which suppresses noise by thresholding
the empirical wavelet coecients. The th...
