Applied researchers often compute weighted means where the weights reflect the relative size of each observation. Despite their common use, the statistical properties of these size-weighted means appear to be poorly understood, as the existing statistical lit…

We study a non-mixture cure model with a covariate change-point for right-censored survival data and develop maximum-likelihood estimation under a smoothed likelihood to handle the non-differentiability induced by the threshold. Assuming exponential latency f…

The Rectified Linear Unit (ReLU) activation function is widely employed in deep learning (DL). ReLU shares structural similarities with censored regression and Tobit models common in econometrics and statistics. Although the conventional Tobit maximum likelih…

This study examined the relationship between the Monetary Policy Rate (MPR) and inflation across five continents from 2014 to 2023 using both Frequentist and Bayesian Linear Mixed Models (LMM). It extends the first part of this research which analyzed the rel…

This paper examines the extent to which competencies taught in Congolese universities match the skills required by the labour market. Using official curricula from the Ministry of Higher and University Education and 1560 LinkedIn job postings (2023-2025), we…

The Central Limit Theorem occasionally results in extremely slow convergence to the Normal distribution, making the corresponding approximation virtually useless (a typical example being the sample correlation coefficient). In most of these cases, there is a…

Determining the causal effect of special education is a critical topic when making educational policy that focuses on student achievement. However, current special education research is facing challenges from persistent selection bias and complex confounding.…

Food insecurity remains a challenge in many sub-Saharan countries and is heavily driven by climate variability. In South Sudan, food insecurity is further exacerbated by incessant sporadic conflict. Understanding the drivers of food insecurity is critical in…

This research evaluates the effect of monetary policy rate and exchange rate on inflation across continents using both Frequentist and Bayesian Generalized Additive Mixed Models (GAMMs). Extending an earlier study that employed Frequentist and Bayesian Linear…

A hyperbolic model for the diffusion of proteins through the blood-cerebrospinal fluid (CSF) barrier revolutionized clinical neurochemistry thirty years ago. The regression curves were informally parametrized based on physiologically-driven constraints. The c…

The goal of this journal is to provide a platform for scientists and academicians all over the world to promote, share, and discuss various new issues and developments in different areas of statistics. All… All articles are open access under a CC BY 4.0 licence, with authors retaining copyright.
Authors submit their manuscript, metadata, and declarations through the portal. There is no submission fee.
The editorial office screens the manuscript for scope, completeness, and formatting before assigning a handling editor.
At least two independent reviewers evaluate the manuscript under single-blind review. Where revisions are required, authors respond point by point.
On acceptance the article processing charge is invoiced and the CC BY 4.0 copyright handover is signed.
The article is copyedited, typeset, and given a DOI, then publishes open access with a permanent link.
Manuscripts must be original and not under consideration elsewhere. Submit in Microsoft Word or LaTeX with figures at 300 dpi minimum. Structure research articles as Abstract, Introduction, Methods, Results, Discussion, and References.
Use the journal's numbered (Vancouver) reference style. Cite sources consecutively in the order they appear, and ensure every reference is complete and retrievable.
