      Article
      Accés obert
      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
      Accés obert
      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
      Accés obert
      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 ...
