摘要
In point estimation, such as other statistical problems, we may confront imprecise concepts. One case is a situation in which observations and parameter are fuzzy. The concept for fuzzy estimators of fuzzy parameters in fuzzy random variables is proposed in this paper. We proposes a new method for uniformly minimum variance unbiased fuzzy (UMVUF) estimation. For this purpose we will make use of a uniformly minimum variance unbiased (UMVU) estimator and we will develop this new method for a fuzzy random sample (X) over tilde (1,) (X) over tilde (2), ..., (X) over tilde (n) is induced by X-1, X-2, ..., X-n on the same probability space.
