In this paper, we derive the general formulae for the moments of a linear functional of the Stein-rule and positive-part Stein-rule estimators (i.e., h′bSRand h′bPSR) in a different way from Phillips (1984). The MSE dominance of h′bPSRover h′bSRand a sufficient condition for h′bSRto dominate a linear functional of the OLS estimator (h′b) are shown. Using the formulae for the moments, we evaluate numerically the first four moments of bSRand bPSR, and examine the bias, variance, MSE, skewness, and kurtosis.
