Comparative Judgement Modeling to Map Forced Marriage at Local Levels (2023)
Working Paper
Seymour, R., Nyarko-Agyei, A., Severn, K., McCabe, H., Kypraios, T., Sirl, D., & Taylor, A. Comparative Judgement Modeling to Map Forced Marriage at Local Levels

Forcing someone into marriage against their will is a violation of their human rights. In 2021, the county of Nottinghamshire, UK, launched a strategy to tackle forced marriage and violence against women and girls. However, accessing information abou...

The Leydig cell biomarker INSL3 as a predictor of age-related morbidity: Findings from the EMAS cohort (2022)
Journal Article
Ivell, R., Heng, K., Severn, K., Antonio, L., Bartfai, G., Casanueva, F. F., …Anand-Ivell, R. (2022). The Leydig cell biomarker INSL3 as a predictor of age-related morbidity: Findings from the EMAS cohort. Frontiers in Endocrinology, 13, Article 1016107. https://doi.org/10.3389/fendo.2022.1016107

Background: Insulin-like peptide 3 (INSL3) is a constitutive hormone secreted in men by the mature Leydig cells of the testes. It is an accurate biomarker for Leydig cell functional capacity, reflecting their total cell number and differentiation sta...

Association of age, hormonal, and lifestyle factors with the Leydig cell biomarker INSL3 in aging men from the European Male Aging Study cohort (2022)
Journal Article
Anand-Ivell, R., Heng, K., Severn, K., Antonio, L., Bartfai, G., Casanueva, F. F., …Ivell, R. (2022). Association of age, hormonal, and lifestyle factors with the Leydig cell biomarker INSL3 in aging men from the European Male Aging Study cohort. Andrology, 10(7), 1328-1338. https://doi.org/10.1111/andr.13220

Background: Aging in men is accompanied by a broad range of symptoms, including sexual dysfunction, cognitive and musculoskeletal decline, obesity, type 2 diabetes, cardiovascular disease and hypertension, organ degeneration/failure, and increasing n...

Manifold valued data analysis of samples of networks, with applications in corpus linguistics (2022)
Journal Article
Severn, K. E., Dryden, I. L., & Preston, S. P. (2022). Manifold valued data analysis of samples of networks, with applications in corpus linguistics. Annals of Applied Statistics, 16(1), 368-390. https://doi.org/10.1214/21-aoas1480

Networks arise in many applications, such as in the analysis of text documents, social interactions and brain activity. We develop a general framework for extrinsic statistical analysis of samples of networks, motivated by networks representing text...

Non?parametric regression for networks (2021)
Journal Article
Severn, K. E., Dryden, I. L., & Preston, S. P. (2021). Non?parametric regression for networks. Stat, 10(1), Article e373. https://doi.org/10.1002/sta4.373

Network data are becoming increasingly available, and so there is a need to develop suitable methodology for statistical analysis. Networks can be represented as graph Laplacian matrices, which are a type of manifold-valued data. Our main objective i... Read More about Non?parametric regression for networks.
