This article reviews the state of multiparameter shrinkage estimators with emphasis on the
empirical Bayes viewpoint, particularly in the case of parametric prior distributions. Some …

Stein's estimator for k normal means is known to dominate the MLE if k ≥ 3. In this article
we ask if Stein's estimator is any good in its own right. Our answer is yes: the positive part …

In 1961, James and Stein exhibited an estimator of the mean of a multivariate normal
distribution having uniformly lower mean squared error than the sample mean. This estimator is …

Sometimes a mathematical result is strikingly contrary to generally held belief even though
an obvi ously valid proof is given. Charles Stein of Stanford University discovered such a …

The normal, Poisson, gamma, binomial, and negative binomial distributions are univariate
natural exponential families with quadratic variance functions (the variance is at most a …

We have tested alternative models of the demand for medical care using experimental data.
The estimated response of demand to insurance plan is sensitive to the model used. We …

A total of 7706 persons are participating in a controlled trial of alternative health-insurance
policies. Interim results indicate that persons fully covered for medical services spend about …

Hay and Olsen (1984) incorrectly argue that a multi-part model, the two-part model used in
Duan et al. (1982,1983), is nested within the sample-selection model. Their proof relies on an …

In contrast to the well-established role of oxidative muscle fibers in regulating whole-body
metabolism, little is known about the function of fast/glycolytic muscle fibers in these processes…

Skeletal muscle must perform different kinds of work, and distinct fiber types have evolved to
accommodate these. Previous work had shown that the transcriptional coactivator PGC-1α …
