A new representation of the diagonal Vech model is given using the Hadamard product. Sufficient conditions on parameter matrices are provided to ensure the positive definiteness of covariance… (More)

Donoho and Johnstone’s (1994) WaveShrink procedure has proven valuable for signal de-noising and non-parametric regression. WaveShrink has very broad asymptotic near-optimality properties. In this… (More)

In a series of papers, Donoho and Johnstone develop a powerful theory based on wavelets for extracting nonsmooth signals from noisy data. Several nonlinear smoothing algorithms are presented which… (More)

Donoho & Johnstone's WaveShrink procedure has proved valuable for function estimation and nonparametric regression. WaveShrink is based on the principle of shrinking wavelet coefficients towards zero… (More)

We study the problem of estimating the log spectrum of a stationary Gaussian time series by thresholding the empirical wavelet coe cients. We propose the use of thresholds t j;n depending on sample… (More)

Exenatide is an incretin mimetic with potential glucoregulatory activity in type 2 diabetes. This randomized, single-blind, placebo-controlled 6-way crossover study assessed exenatide's effect on… (More)

Many nonparametric regression procedures are based on “subset selection”: they choose a subset of carriers from a large or even infinite set, and then determine the coefficients of the chosen… (More)

We present the application of wavelet-based de-noising techniques to the demodulation of digital communication signals. These techniques are related to those originally devised by Donoho and… (More)

Wavelet shrinkage (WaveShrink) is a relatively new technique for nonparametric function estimation that has been shown to have asymptotic near-optimality properties over a wide class of functions. As… (More)
