SS-PALT for Logistic-Exponential Distribution with Adaptive Type-I Progressively Hybrid Censored Data
Abstract This study investigates the application of adaptive Type-I progressive hybrid censoring techniques for the estimation of failure times in step-stress partially accelerated life tests. We employ a Logistic-Exponential distribution to model the lifetimes of the test units and derive the…

The Q-Lindley Distribution: Goodness-of-Fit Tests, Modeling, Inference, and Applications
Abstract This paper introduces the Q-Lindley distribution (QLD), a new one-parameter model for lifetime and reliability data derived from the affine exponential family. We derive its main statistical properties and estimate the parameter using maximum likelihood. The performance of the QLD is…

A Class of Bell-Shaped Distributions with Bounded Supports
Abstract In this article we introduce a new family of parametrized density functions that are bell-shaped and supported by a finite interval (0, 1). The corresponding random variable X assumes the structure $$X=W+{\Theta }V$$ where (W, V) is a bivariate Dirichlet random vector with parameters…

The Sine–Fréchet G Family of Continuous Distributions: Sub-models, Properties, Simulation and Applications
Abstract Many real-world datasets exhibit skewness, heavy tails, and complex hazard-rate shapes that classical lifetime distributions and several existing generalized families fail to capture adequately. To address these limitations, this paper introduces the Sine–Fréchet-G family of continuous…

Factorial ANOMC Tests: A Comparative Analysis of Type I Error and Power under Multifactor Experimental Designs
Abstract This study introduces a factorial extension of the Analysis of Means with Covariate (ANOMC), building on the classical ANOM framework by incorporating auxiliary covariate information. The proposed factorial ANOMC approach is designed for experiments involving two fixed factors and a…

Absolutely Continuous Bivariate Modified Weibull Distribution: Properties and Estimation
Abstract A Block-Basu bivariate exponential (BBBE) distribution is one of the most popular and widely used absolutely continuous bivariate distributions. Later, Kundu and Gupta (Stat Method 7:464–477, 2010) obtained the Block-Basu bivariate Weibull (BBBW) distribution. Extensive work has been done…

Modelling the Proportions with Excessive Endpoints Based on a Generalized Lindley Binomial Model
Abstract This paper introduces the generalized Lindley binomial (GLB) distribution, a novel model for analyzing proportional data with excessive endpoint observations. The GLB distribution is derived by compounding the binomial distribution with a generalized three-parameter Lindley distribution…

Improved Estimation of Rates of Glaucoma Progression Using Spatial Two-Fold Linear Mixed Models
Abstract Visual field testing is essential for detecting glaucomatous damage. Traditional approaches such as pointwise linear regression often fail to account for the spatial correlations and hierarchical structure among test locations. We propose a two-fold linear mixed model that incorporates…

An Extended Spherical Fuzzy TAOV Model for Multi-Criteria Group Decisions under Heterogeneity and Correlated Criteria
Abstract This paper develops an extended spherical fuzzy multi-criteria group decision-making (MCGDM) framework that integrates hybrid weighting with the total area method based on orthogonal vectors (TAOV). The main motivation is to address key limitations in existing MCGDM approaches by…

Bifurcation Analysis of a Discrete-Time Prey-Predator Model: Theory and Numerical Continuation
Abstract This paper presents a comprehensive analysis of the bifurcation behavior of a two-dimensional predator-prey model described by a system of nonlinear difference equations. The study investigates the behavior of the system under different parameter regimes using both analytical and numerical…

Inverse hill statistic for the novel four-parameter extrapolation Weibull scheme, an algorithmic design approach
Abstract One of the most popular methods for assessing the distribution tail thickness parameter (tail index) of a two-parameter PD is the Hill estimator, derived from order statistics. For reliability evaluations and engineering design, an accurate assessment of the distribution’s tails is…

Construction of Group Sampling Plans for Lot Acceptance Using Limited Conventional and Expected Weighted-Average of Risks
Abstract The group sampling plans represent an enhancement of single sampling plans, wherein evaluators assess multiple items concurrently, thereby optimizing both time and cost. In this paper, an optimal group acceptance sampling plan under time-censoring is proposed when the lifetime of a product…

Interpretation of Large Datasets via a New Regression Analysis Based on Reverse Discretization
Abstract The discrete point objects of a Dataset are transformed to continuous functions by the proposed method of Reverse Discretization. Each point is defined by its coordinates xr and yr and it carries the information mr (mass, price, velocity etc.). The information is treated as a field…

Estimation for a Distribution with Increasing or Bathtub-Shaped Distribution Based on Ranked Set Samples
Abstract The traditional ranked set sampling (RSS) scheme can be viewed as an alternative to the simple random sampling (SRS) scheme in many lifetime scenarios. Over the years, numerous RSS-type methods have been proposed in the literature such as the ones with unequal sample sizes. This paper…

Symbolic Interval-Valued Regression Model
Abstract Symbolic data analysis can provide statistical inferences for macroscale data while preserving as much information as possible from microscale data. In this study, we focus on the symbolic interval-valued regression model. The microdata are reorganized into intervals by using the largest…
