New classes at Specific Age: Properties and Testing hypotheses

TESTING STATISTICAL HYPOTHESES UNDER FUZZY DATA AND BASED ON A NEW SIGNED DISTANCE

This paper deals with the problem of testing statisticalhypotheses when the available data are fuzzy. In this approach, wefirst obtain a fuzzy test statistic based on fuzzy data, and then,based on a new signed distance between fuzzy numbers, we introducea new decision rule to accept/reject the hypothesis of interest.The proposed approach is investigated for two cases: the casewithout nuisance p...

Testing fuzzy hypotheses with vague data

The problem of testing fuzzy hypotheses in the presence of vague data is considered. A new method based on the necessity index of strict dominance (NSD) is suggested. An example hoe to apply the proposed test in statistical quality control is shown.

Some Aging Classes of Life Distributions at Specific Age

Abstract We introduce some properties of the new better than used in convex ordering at age t0 (NBUC − t0) and new better than used of second order(2) at age t0 (NBU(2)−t0) classes of life distributions,where the survival probability at age 0 is greater than or equal to the conditional survival probability at specified age t0 > 0. Preservation properties of the two classes under various reliabi...

Testing New Hypotheses Regarding Ebolavirus Reservoirs

Despite a relatively long search for the origin of ebolaviruses, their reservoirs remain elusive. Researchers might have to consider testing alternative hypotheses about how these viruses persist and emerge to advance ebolavirus research. This article aims to encourage researchers to bring forward such hypotheses, to discuss them scientifically and to open alternative research avenues regarding...
