Point Estimation and Confidence Set in a Parallelism Model: an Empirical Bayes Approach

When several simple regression models are assumed to have similar slopes, empirical Bayes methods can efficiently process tis vague information by estimating the hyperparameters of a conjugate prior. The shrinkage estimators we obtain are shown to be minimax and, furthermore, dominate usual confidence regions in terms of coverage probability.
