Is Cp an empirical Bayes method for smoothing parameter choice?
The Cp selection criterion is a popular method to choose the smoothing parameter in spline regression. Another widely used method is the generalized maximum likelihood (GML) derived from a normal-theory empirical Bayes framework. These two seemingly unrelated methods, have been shown in Efron (Ann. Statist. 29 (2001) 470) and Kou and Efron (J. Amer. Statist. Assoc. 97 (2002) 766) to be actually...
متن کاملAn empirical Bayes method for gene expression analysis in R
In recent years the new technology of microarrays has made it feasible to measure expression of thousands of genes to identify changes between different biological states. In such biological experiments we are confronted with the problem of high-dimensionality because of thousands of genes involved and at the same time with small sample sizes (due to limited availability of cases). The set of d...
متن کاملEmpirical Bayes estimation smoothing of relative risks in disease mapping
A common index of disease incidence and mortality is the standardized mortality ratio (SMR). The SMR is a reliable measure of relative risk for large geographical regions such as countries or states, but may be unreliable for small areas such as counties. This paper reviews several empirical Bayes methods for producing smoothed estimates of the SMR as well as the conditional autoregressive proc...

15 صفحه اولAn Improved Bayes Empirical Bayes Estimator
Consider an experiment yielding an observable random quantity X whose distribution Fθ depends on a parameter θ with θ being distributed according to some distribution G0. We study the Bayesian estimation problem of θ under squared error loss function based on X, as well as some additional data available from other similar experiments according to an empirical Bayes structure. In a recent paper,...
