Abstract
In statistical inference, the point estimation problem is very crucial
and has a wide range of applications. When, we deal with some concepts
such as random variables, the parameters of interest and estimates may be
reported/observed as imprecise. Therefore, the theory of fuzzy sets plays an
important role in formulating such situations. In this paper, we rst recall the
crisp uniformly minimum variance unbiased (UMVU) and Bayesian estimators
and then develop the concept of fuzzy estimators for fuzzy parameters based
on fuzzy random variables.
