The conditional mean value has applications in regression analysis and financial mathematics, because they are used it. We can find papers from recent years that use the fuzzy cases. As intuitionstic sets an extension of sets, we will try to define a for intuitionistic case. crisp events was first studied by V. Valenčáková 2009. She Gödel connectives. Her approach only be special cases events, ...

In 2001 we introduced the notions of possibilistic mean value and variance of fuzzy numbers. In this paper we list some works that use these notions. We shall mention some application areas as well. 1 Possibilistic mean value, variance, covariance and correlation A fuzzy number A is a fuzzy set R with a normal, fuzzy convex and continuous membership function of bounded support. The family of fu...

The mean and the variance value of a random variable play an important role in statistical analysis. Sometimes the available observations are not precise, and we want to test the hypotheses of mean and variance in such environment. Hence, in this paper, we first extend and introduced L2−metric based on imprecise (fuzzy) observations, and then, the concepts of fuzzy test statistics are defined b...
