Neutrosophic Beta Distribution with Properties and Applications [PDF]
Neutrosophic Sets and Systems, 2021 This research is an extension of classical statistics distribution theory as the theory did not deal with the problems having ambiguity, impreciseness, or indeterminacy.

Bernstein-type bounds for beta distribution [PDF]
Modern Stochastics: Theory and Applications, 2023 This work obtains sharp closed-form exponential concentration inequalities of Bernstein type for the ubiquitous beta distribution, improving upon sub-Gaussian and sub-gamma bounds previously studied in this context.

Beta-PSMC: uncovering more detailed population history using beta distribution. [PDF]
BMC Genomics, 2022 Background Inferring the demographic history of a population is essential in population genetic studies. Though the inference methods based on the sequentially Markov coalescent can present the population history in detail, these methods assume that the ...

The initial mass function modeled by a left truncated beta distribution [PDF]
, 2013 The initial mass function (IMF) for the stars is usually fitted by three straight lines, which means seven parameters. The presence of brown dwarfs (BD) increases to four the straight lines and to nine the parameters.

Using the Beta distribution in group-based trajectory models. [PDF]
BMC Med Res Methodol, 2018 BackgroundWe demonstrate an application of Group-Based Trajectory Modeling (GBTM) based on the beta distribution. It is offered as an alternative to the normal distribution for modeling continuous longitudinal data that are poorly fit by the normal ...

The Inertia Weight Updating Strategies in Particle Swarm Optimisation Based on the Beta Distribution [PDF]
, 2015 The presented paper deals with the comparison of selected random updating strategies of inertia weight in particle swarm optimisation. Six versions of particle swarm optimization were analysed on 28 benchmark functions, prepared for the Special Session ...

Proximal Policy Optimization with Continuous Bounded Action Space via the Beta Distribution [PDF]
IEEE Symposium Series on Computational Intelligence, 2021 Reinforcement learning methods for continuous control tasks have evolved in recent years generating a family of policy gradient methods that rely primarily on a Gaussian distribution for modeling a stochastic policy.

Stein's method of exchangeable pairs for the Beta distribution and generalizations [PDF]
, 2015 . We propose a version of Stein’s method of exchangeable pairs, which, given a suitable exchangeable pair (W,W ) of real-valued random variables, suggests the approximation of the law of W by a certain absolutely continuous distribution, which is ...
