A Finite-State Stationary Process with Long-Range Dependence and Fractional Multinomial Distribution

Fractal and Fractional, 2022
We propose a discrete-time, finite-state stationary process that can possess long-range dependence. Among the interesting features of this process is that each state can have different long-term dependency, i.e., the indicator sequence can have a ...

Data Clustering for Identification of Building Conditions Using Hybrid Multivariate Multinominal Distribution Soft Set (MMDS) Method

JOIV: International Journal on Informatics Visualization, 2022
Identifying building conditions for user safety is an urgent matter, especially in earthquake-prone areas. Clustering buildings according to their conditions in the categories of danger, vulnerable, normal, and safe is important information for residents

Variable Selection in General Multinomial Logit Models [PDF]

, 2012
The use of the multinomial logit model is typically restricted to applications with few predictors, because in high-dimensional settings maximum likelihood estimates tend to deteriorate.

Multinomial logit bias reduction via Poisson log-linear model [PDF]

, 2010
It is shown how to obtain the bias-reducing penalized maximum likelihood estimator for the parameters of a multinomial logistic regression by using the equivalent Poisson log-linear model.

Gaudin Model for the Multinomial Distribution

Annales Henri Poincaré, 2023
The goal of the paper is to analyze a Gaudin model for a polynomial representation of the Kohno-Drinfeld Lie algebra associated with the multinomial distribution. The main result is the construction of an explicit basis of the space of polynomials consisting of common eigenfunctions of Gaudin operators in terms of Aomoto-Gelfand hypergeometric series ...

A Neural Network Approach for Pricing Correlated Health Risks

Risks
In recent years, the actuarial literature involving machine learning in insurance pricing has flourished. However, most actuarial machine learning research focuses on property and casualty insurance, while using such techniques in health insurance is yet

Parameter Estimation of the Dirichlet Distribution Based on Entropy

Axioms, 2023
The Dirichlet distribution as a multivariate generalization of the beta distribution is especially important for modeling categorical distributions. Hence, its applications vary within a wide range from modeling cell probabilities of contingency tables ...

Non-normal Distributions Commonly Used in Health, Education, and Social Sciences: A Systematic Review

Frontiers in Psychology, 2017
Statistical analysis is crucial for research and the choice of analytical technique should take into account the specific distribution of data. Although the data obtained from health, educational, and social sciences research are often not normally ...

Multiple Testing with Heterogeneous Multinomial Distributions [PDF]

Biometrics, 2016
SummaryStandard false discovery rate (FDR) procedures can provide misleading inference when testing multiple null hypotheses with heterogeneous multinomial data. For example, in the motivating study the goal is to identify species of bacteria near the roots of wheat plants (rhizobacteria) that are moderately or strongly associated with productivity ...
