Shrinkage confidence intervals for the normal mean: Using a guess for greater efficiency

Abstract: If the unknown mean of a univariate population is sufficiently close to the value of an initial guess then an appropriate shrinkage estimator has smaller average squared error than the sample mean. This principle has been known for some time, but it does not appear to have found extension to problems of interval estimation. The author presents valid two-sided 95% and 99% "shrinkage" confidence intervals for the mean of a normal distribution. These intervals are narrower than the usual interval based on the Stu… Show more
