*Abstract*

Decision-theoretic approach is applied to the random-effects model of
meta-analysis.

A canonical representation of the restricted likelihood function is
obtained. The relationship between the mean effect estimators and the
heterogeneity variance estimators is explored via this representation. An
explicit form of the variance of weighted means statistics  determined by
means of a quadratic form is found. The behavior of the mean squared error
for large heterogeneity variance is elucidated. It is noted that the sample
mean is not admissible nor minimax when the number of studies is larger
than three.
