Weighted Half Exponential Power Distribution and Associated Inference

, 2016
The weighted exponential distribution has been generalized by many authors in recent years. Here, we introduce a new generalization, called the weighted half exponential power distribution, that can be used to model negative or positive skewed data ...

Parametric Inference for a Multicomponent Stress–Strength Reliability Model With Kumaraswamy Distribution Under Ordered Ranked Set Sampling

Journal of Mathematics, Volume 2026, Issue 1, 2026.
Assessing reliability in systems with dual stress constraints needs a flexible model and effective sampling methods. A framework using the Kumaraswamy distribution is set up for multicomponent stress and strength systems. Data collection is done through ordered ranked set sampling, leveraging the unified theory of generalized order statistics to ...

Global convergence and ascent property of a cyclic algorithm used for statistical analysis of crash data

, 2018
In this paper, we consider an estimation algorithm called cyclic iterative algorithm (CA) that is used in statistics to estimate the unknown vector parameter of a crash data model.

Comparative Analysis and Practical Applications of Cubic Transmutations for the Pareto Distribution

International Journal of Mathematics and Mathematical Sciences, Volume 2025, Issue 1, 2025.
Transmutation is a technique for extending classical probability distributions in order to give them more flexibility. In this paper, we are interested in cubic transmutations of the Pareto distribution. We establish a general formula that unifies the three existing cubic transmuted Pareto (CTP) distributions and facilitates the derivation of three new

Estimating the effects of staggered interventions with count and binary outcomes: a simulation study

Journal of Causal Inference
Difference-in-Differences and Event-Study regression estimators are commonly used to estimate treatment effects. However, when effects are heterogeneous, the standard two-way fixed effects (TWFE) regression can provide biased estimates. Recent literature

An Alternative Type II Claims Pareto Model for Reliability and Bimodal Risk Analysis: Copulas, Properties, Mathematical Modeling, and Actuarial Case Study

Journal of Mathematics, Volume 2025, Issue 1, 2025.
This article aims to present a new type‐II claims Pareto extension for statistical reliability and actuarial analysis. The new probabilistic density can be simplified in terms of the baseline densities. Some new bivariate types were developed under some copula approaches.

Introducing the new arcsine-generator distribution family: An in-depth exploration with an illustrative example of the inverse weibull distribution for analyzing healthcare industry data

Journal of Radiation Research and Applied Sciences
The study is about a novel Arcsin-function based generator of new families of distributions. We chose the inverse Weibull distribution as the reference distribution to see if the generator could be employed.

On adaptive optimal prediction of Ornstein-Uhlenbeck process

, 2017
This paper suggests predictors for the Ornstein-Uhlenbeck process based on the truncated estimators of parameters. For these estimators there are established the asymptotic and non-asymptotic properties with guaranteed accuracy. Strong consistency of the

Improved Efficiency in Generalized Poisson Hurdle Model Estimation Using Restricted and Shrinkage Methods

Journal of Mathematics, Volume 2025, Issue 1, 2025.
This paper investigates the use of shrinkage estimators in the generalized Poisson hurdle (GPH) model for count data analysis. The GPH model effectively handles data with both excess zeros and over‐ or underdispersion. We propose shrinkage estimators to improve parameter estimation in this model and analyze their asymptotic properties, including biases
