New Fuzzy Extensions on Binomial Distribution
Axioms, 2022 The use of discrete probabilistic distributions is relevant to many practical tasks, especially in present-day situations where the data on distribution are insufficient and expert knowledge and evaluations are the only instruments for the restoration of

Plithogenic Probability & Statistics are generalizations of MultiVariate Probability & Statistics [PDF]
Neutrosophic Sets and Systems, 2021 In this paper we exemplify the types of Plithogenic Probability and respectively Plithogenic Statistics. Several applications are given. The Plithogenic Probability of an event to occur is composed from the chances that the event occurs with respect to ...

Variable grouping in multivariate time series via correlation [PDF]
, 2001 The decomposition of high-dimensional multivariate time series (MTS) into a number of low-dimensional MTS is a useful but challenging task because the number of possible dependencies between variables is likely to be huge.

On Distribution Characteristics of a Fuzzy Random Variable
Austrian Journal of Statistics, 2018 In this paper, rst a new notion of fuzzy random variables is introduced. Then, using classical techniques in Probability Theory, some aspects and results associated to a random variable (including expectation, variance, covariance, correlation coecient ...
