Sine Error Function‐Generated Family of Distributions: Estimations and Applications

International Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.
In recent times, researchers have resorted to using trigonometric and error function‐generated families of distributions for extending baseline distributions due to their parsimonious and flexible nature. The study proposed the sine error function‐generated family of distributions and derived the statistical properties of the proposed family.

Exponentiated Extended Weibull-power Series class of Distributions [PDF]

, 2015
In this paper, we introduce a new class of distributions by compounding the exponentiated extended Weibull family and power series family. This distribution contains several lifetime models such as the complementary extended Weibull-power series ...

Some Results on Exponentiated Weibull Distribution via Dual Generalized Order Statistics

, 2022
In this paper, we use the concept of dual generalized order statistics dgos which was given by Pawlas and Syznal (2001). By using this, we obtain the various theorems and some relations through ratio and inverse moment by using exponentiated-Weibull ...

Employing the Inverse Weibull Failure Time Model to Estimate Some of the Reliability Metrics of k‐Out‐of‐n Systems

Journal of Applied Mathematics, Volume 2026, Issue 1, 2026.
This paper presents a new approach to determine the mean time to system failure (MTSF) and reliability function of k‐out‐of‐n systems with independent and identically distributed components following the inverse Weibull (IW) distribution. The system remains operational when at least k of its n components function properly.

Developing New Bivariate Distributions With Advanced Estimation Methods for Interdisciplinary Data Analysis

Journal of Mathematics, Volume 2026, Issue 1, 2026.
This paper proposes a novel bivariate odd beta prime Fréchet (BOBPF) distribution constructed through the application of the Farlie–Gumbel–Morgenstern (FGM) copula function. The new model, called the BOBPF‐FGM, is engineered to address the persistent challenge of modeling positively skewed and heavy‐tailed bivariate data that exhibit complex ...

The Exponentiated Kumaraswamy-Weibull Distribution with Application to Real Data

, 2017
A new five-parameter lifetime distribution called the exponentiated Kumaraswamy-Weibull distribution is introduced. It includes several important sub-models as special cases such as exponentiated Weibull, Kumaraswamy-Weibull, exponentiated exponential ...

The Exponentiated Inverted Weibull Distribution

, 2012
The exponentiated -parent distribution is a generalization of the standard parent distribution. [7] introduced a simple generalization to weibull distribution namely the exponentiated weibull distribution.

Power‐Transformed Bradford Distribution: Properties, Quantile Regression, and Empirical Illustrations

Journal of Mathematics, Volume 2026, Issue 1, 2026.
The representation of uncertainty that defines random processes constrained by the unit support, like rates and proportions, is a necessary undertaking in various fields of study, including economics, psychology, and public health. Although the beta distribution is the default option, it can be unsuitable for large‐scale practical uses because of some ...

Arctan inverted exponentiated Weibull model with actuarial measures and applications to insurance and inflation data

Scientific African
Trigonometric-based statistical models have gained attention in recent years because of their ability to capture complex data patterns. In this article, we propose a new extension of the inverted exponentiated Weibull (IEW) distribution by embedding it ...

Bayesian Reliability Assessment of Birnbaum–Saunders Model With Partial Prior Information Using Improved Adaptive Progressively Censored Samples

Journal of Mathematics, Volume 2026, Issue 1, 2026.
This paper investigates inference for the Birnbaum–Saunders lifetime model under an improved adaptive Type‐II progressive censoring scheme. We develop both classical and Bayesian methodologies to estimate model parameters, the reliability function, and the hazard rate.
