VarReg: An R package for semi-parametric variance regression
SoftwareXVariance regression is used to model heteroscedasticity in terms of covariates. Algorithms already exist but they may face computational instability due to the required parameter constraints.

Obesity Reviews, Volume 27, Issue 8, August 2026.ABSTRACT Objective This systematic review and meta‐analysis aimed to identify common life‐course body mass index (BMI) trajectories (childhood/adulthood to adulthood) and their impact on risk of cancer overall and cancer at different sites in adulthood. Methods Observational studies were identified that assessed the association of BMI trajectories with

Longitudinal Data Regression Analysis Using Semiparametric Modelling
Revstat Statistical JournalZhang, Leng and Tang (2015) propose joint parametric modelling of the means, variances, and the correlations by decomposing the correlation matrix via hyperspherical co-ordinates and show that this results unconstrained parameterization, fast ...

Strain, Volume 62, Issue 4, August 2026.A new methodology shows that current multiaxiall fatigue criteria are not sufficient. ABSTRACT In the present work, mappings of two invariants of the true strain tensor, K2$$ {K}_2 $$ that measures the magnitude of the distortion and K3$$ {K}_3 $$ that quantifies the mode of distortion, are used to investigate the multiaxial fatigue of AE2 and AE42 ...

Fuzzy Semi-Parametric Regression Based on Z-numbers
Transactions on Fuzzy Sets and SystemsSemi-parametric regression models are highly valued for combining parametric structure with nonparametric flexibility. However, in real-world situations involving data with inherent uncertainty and variable reliability, classical fuzzy numbers are ...
