## Abstract (arXiv)

Empirical Bayes methods use the data from parallel experiments, for instance, observations Xk~N(Thetak,1) for k=1,2,ldots,N, to estimate the conditional distributions Thetak|Xk. There are two main estimation strategies: modeling on the θ space, called "g-modeling" here, and modeling on the x space, called "f-modeling." The two approaches are described and compared. A series of computational formulas are developed to assess their frequentist accuracy. Several examples, both contrived and genuine, show the strengths and limitations of the two strategies.
