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 ...

Institute of Communications Engineering, ECE, NCTU 4 Unit 1: MinimumVariance Unbiased Estimator Sau-Hsuan Wu Can be have some performance measure? We model the data by its probability density function (PDF), assuming that the data are inherently random. As an example: We have a class of PDF...
optimize the MSE with respect to the class of unbiased estimators. The Minimum Variance UnBiased (MVUB) estimator is defined as ˜ θ = arg min ˆ θ : E[ ˆ θ]=θ ∗ E[∥ ˆ θ −E ˆ θ∥ 2 2 ] 1 Lecture 16: Minimum Variance Unbiased(MVUB) Estimators 2 ...
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...

1) Minimum variance quadratic unbiased estimator 最小方差二次无偏估计 2) UMVIQUE 一致最小方差不变二次无偏估计 1. In the paper,the MINQE(U,I) of variance components is given,and the necessary and sufficient conditions for the MINQE(U,I) to beUMVIQUEhave been obtained. ...
We also define the minimum-variance pseudo-unbiased low-rank estimator which minimizes the variance of estimate among all pseudo-unbiased low-rank estimators. The pseudo-unbiased low-rank estimator and the minimum-variance pseudo-unbiased low-rank estimator are respectively natural generalizations of the...
In a variance components model for normally distributed data, for a specified vector of linear combinations of the variance components, necessary and sufficient conditions are given under which the vector has a uniformly minimum variance unbiased translation-invariant estimator. The competing class of es...
ECE531 Screencast 1.4: Minimum Variance Unbiased Estimators Finding MVU Estimators There is no “plug-and-chug” method that you can always follow to find an MVU estimator. We will cover two common approaches that work in many cases: 1. The Cramer-Rao lower bound (Kay I: Chapters 3-4...
