Determining the minimum variance of an unbiased estimator constitutes a fundamental topic in mathematical statistics. Two primary results are the Cramér–Rao inequality, which gives a lower bound on the variance of an unbiased estimator, and the Rao–Blackwell theorem, which supplies a method for ...
A general model is put forward in which the likelihood depends on an unknown parameter [theta] and the question addressed is to find conditions under which a minimum variance unbiased estimator (MVUE) exists. Two New Zealand pioneer econometricians 2, as well as the interval based on the unifo...
摘要: Addresses the problem of estimating the probability of an odd number of successes in a an independent amount of Bernoulli trials in minimum variance unbiased fashion. Aspects of parametric estimation theory which are generated by this problem....

This paper presents a novel low-rank linear statistical estimator named minimum-variance pseudo-unbiased low-rank estimator for applications to ill-conditioned linear inverse problems. Based on a simple fact : 'any low-rank estimator can not be a (uniformly) unbiased estimator', we introduce pseudo...
We derive the minimum variance quadratic unbiased estimator (MIVQUE) of the variance of the components of a random vector having a compound normal distribution (CND). We show that the MIVQUE converges in probability to a random variable whose distribution is essentially the mixing distribution chara...

This paper proposes a novel estimator named minimum-variance pseudo-unbiased reduced-rank estimator (MV- PURE) for the linear regression model, designed specially for the case where the model matrix is ill-conditioned and the unknown deterministic parameter vector to be estimated is subjected to know...
