We consider confidence sets for the mean of a multivariate normal distribution with unknown covariance matrix of the form \_ 2 I. The coverage probability of the usual confidence set is shown to be improved asymptotically by centering at a shrinkage estimator.

## Abstract Familyβbased association tests (FBATs) provide simple and powerful tests to detect association between a genetic marker and a diseaseβsusceptibility locus, manifest in subjects by a phenotype or disease trait. Here we propose a new class of conditional tests for familyβbased association
