Abstract:
The definition of a decision function with asymptotically ($n\to\infty$) uniformly minimal $d$-risk
is presented in the framework of the general theory of statistical inference.
Using this definition, we prove that the maximum likelihood estimate has asymptotically uniformly minimal $d$-risk.
This extends one result by
I. N. Volodin and A. A. Novikov [Theory Probab. Appl.,
38 (1994), pp. 118–128] for shrinking priors to the general class of continuous distributions. The proof uses the asymptotic representation of the posterior risk function, as obtained in
[A. A. Zaikin, J. Math. Sci. (N.Y.), 229 (2018), pp. 678–697].
Keywords:$d$-risk, posterior risk asymptotics, maximum likelihood estimate.
