Abstract
Assume that the observed sample y1…,yn is approximately normalized by the square root transformation, x = 2(y1/2)-1) which belongs to the Box-Cox family of normalizing transformations. The unknown mean of the original y’s sample is a quadratic function of the normal parameters of the transformed sample We study the behavior of a natural estimator of this and more general quadratic functions of normal parameters and obtain a necessary and sufficient condition for its admissibility under quadratic loss. In the case of inadmissibility, a class of better estimators is exhibited.
