Estimating the means and the covariances of fuzzy random variables

Alexey Shvedov

Applied Econometrics, 2016, vol. 42, 121-138

Abstract: At present, methods of fuzzy mathematics are applied in different fields. For example, fuzzy numbers can be used to model returns of assets in portfolio selection problem when historical data is unavailable. While for other assets possibility of using random variables should be kept. This paper presents new estimators of the means and the covariances of fuzzy random variables. Unbiasedness and consistency of these estimators are established.
