所以,在实际应用中,我们可以约束偏差为 0 ,从而求出方差最小的估计量,这种估计量称为最小方差无偏估计量(minimum variance unbiased estimation, MVUE)。 最小方差无偏估计量将估计量的误差 (\hat{\theta}-\theta) 的PDF集中在 0 附近,因此估计量误差很大的可能性很小。 扩展到矢量参数 假设\pmb{\theta}=[...

Jani and Dave [19] have studied the problem of minimum variance unbiased estimation in a class of exponential family of distributions. They have shown that if X 1 , X 2 , . . . , X n be a random sample from density of the type given in (4) and the p.d.f. of its complete su...
Under a stressstrength model, this is reliability of an item. Under independent setup, there are different approaches for the estimation of such reliability. Here, estimation is considered under the dependent case. Under bi-variate setup uniformly minimum variance unbiased estimator is obtained. Also...
