โœฆ Synopsis

The problem of estimating the common mean ~ of k independent and univariate inverse Gaussian populations IG(#, Ai), i = 1,..., k with unknown and unequal A's is considered. The difficulty with the maximum likelihood estimator of ]~ is pointed out, and a natural estimator/5 of/~ along the lines of Graybill and Deal is proposed. Various finite sample properties and some decision-theoretic properties of ~ are discussed.

Consider the problem of estimating the common mean of several normal populations with unknown and possibly unequal variances under the squared error loss function. The well-known unbiased estimator of the common mean is the Graybill-Deal estimator. The general admissibility (or otherwise) of this es
