Generalised Exponential Families and Associated Entropy Functions

open access: yesEntropy, 2008
A generalised notion of exponential families is introduced. It is based on the variational principle, borrowed from statistical physics. It is shown that inequivalent generalised entropy functions lead to distinct generalised exponential families.

The Exponential Dispersion Model Generated by the Landau Distribution—A Comprehensive Review and Further Developments

open access: yesMathematics, 2023
The paper comprehensively studies the natural exponential family and its associated exponential dispersion model generated by the Landau distribution. These families exhibit probabilistic and statistical properties and are suitable for modeling skewed ...

On the Limiting Behaviour of the Fundamental Geodesics of Information Geometry

open access: yesEntropy, 2017
The Information Geometry of extended exponential families has received much recent attention in a variety of important applications, notably categorical data analysis, graphical modelling and, more specifically, log-linear modelling.

Frequency Analysis of Extreme Events Using the Univariate Beta Family Probability Distributions

open access: yesApplied Sciences, 2023
This manuscript presents three families of distributions, namely the Beta, Beta Prime and Beta Exponential families of distributions. From all the distributions of these families, 14 statistical distributions of three, four and five parameters are ...

On the Notion of Reproducibility and Its Full Implementation to Natural Exponential Families

open access: yesMathematics, 2021
Let F=Fθ:θ∈Θ⊂R be a family of probability distributions indexed by a parameter θ and let X1,⋯,Xn be i.i.d. r.v.’s with L(X1)=Fθ∈F. Then, F is said to be reproducible if for all θ∈Θ and n∈N, there exists a sequence (αn)n≥1 and a mapping gn:Θ→Θ,θ⟼gn(θ ...

Pseudo-free families of computational universal algebras

open access: yesJournal of Mathematical Cryptology, 2020
Let Ω be a finite set of finitary operation symbols. We initiate the study of (weakly) pseudo-free families of computational Ω-algebras in arbitrary varieties of Ω-algebras.

A Comparison of the Smoothing Constant Values Among Exponential Smoothing Methods in Commodity Prices Forecasting

open access: yesJurnal RESTI (Rekayasa Sistem dan Teknologi Informasi), 2022
Commodity prices forecasting is one of the business functions to estimate future demand based on past data trend. This study aims to implement a trial and error technique of the constant (alpha α) value in the exponential smoothing method.

Itô-vector projection filter for exponential families

open access: yesResults in Applied Mathematics
In this paper, we study the application of Itô-vector projection [1] to the optimal filtering problem. The algorithm projects one SDE to another, possibly lower dimensional, SDE by minimizing an Itô–Taylor expansion of the local projection error’s L2 ...

A New Family of Exponential Type Estimators in the Presence of Non-Response

open access: yesJournal of Mathematical and Fundamental Sciences, 2021
We propose families of estimators for the population mean using an exponential function in case of non-response. This situation is examined under two cases, Case I and II. The bias, MSE and minimum MSE are separately obtained for both cases.

On Sheffer polynomial families

open access: yes4 open, 2019
Attention is focused to particular families of Sheffer polynomials which are different from the classical ones because they satisfy non-standard differential equations, including some of fractional type.
