In recent years many papers have been devoted to the analysis and applications of negations finite probability distributions (PD), first considered by Ronald Yager. This paper gives a brief overview some formal results on definition properties PD. Negations PD are generated negators values transforming element-by-element into negation Negators non-increasing functions values. There two types ne...

Statistical frequency analysis is the most common procedure for the analysis of flood data at a gauged location thatin first step it is needed to select a model to represent the population. Among them, the central moment has been themost common and widely used, and with the using of computers, the application of the maximum likelihood hasincreased. This research was carried out in order to reco...

In the study of a unified treatment of uncertainty modelled by means of combining probability and fuzzy set theory, Goodman [4] pointed out the equivalence of a fuzzy set and a class of random sets. Wang and Sanchez [13] introduced the theory of falling shadows which directly relates probability concepts with the membership function of fuzzy sets. Falling shadow representation theory shows us t...
