  • A review of the results on the Stein approach for estimators improvement 

    Voinov, V. G. (Vasilii Grigo'evich); Nikulin, M. S. (Institut d'Estadística de Catalunya, 1995)
    Article
    Open Access
    Since 1956, a large number of papers have been devoted to Stein's technique of obtaining improved estimators of parameters, for several statistical models. We give a brief review of these papers, emphasizing those aspects ...
  • On the problem of the means of weighted normal populations 

    Nikulin, M. S.; Voinov, V. G. (Vasilii Grigo'evich) (Institut d'Estadística de Catalunya, 1995)
    Article
    Open Access
    An analytical problem, which arises in the statistical problem of comparing the means of two normal distributions, the variances of which -as well as their ratio- are unknown, is well known in the mathematical statistics ...
  • Unbiased estimators of multivariate discrete distributions and chi-square goodness-of-fit test 

    Nikulin, M. S.; Voinov, V. G. (Vasilii Grigo'evich) (Institut d'Estadística de Catalunya, 1993)
    Article
    Open Access
    We consider the problem of estimation of the value of a real-valued function u(θ), θ = (θ1, ..., θk)T, on the basis of a sample from non-truncated or truncated multivariate Modified Power Series Distributions. Using the ...
