A two-level multivariate response model for data with latent structures (2025)
Journal Article
Zhang, Y., Einbeck, J., & Drikvandi, R. (online). A two-level multivariate response model for data with latent structures. Statistical Modelling, https://doi.org/10.1177/1471082X241313024

A novel approach is proposed for analysing multilevel multivariate response data. The approach is based on identifying a one-dimensional latent variable spanning the space of responses, which then induces correlation between upper-level units. The la...

We consider situations in which the clustering of some multivariate data is desired, which establishes an ordering of the clusters with respect to an underlying latent variable. As our motivating example for a situation where such a technique is desi... Read More about Directed Clustering of Multivariate Data Based on Linear or Quadratic Latent Variable Models.

Using linear mixed models to compare a self-assessed frailty score with clinician assessed scores in patients approaching major surgery (2024)
Presentation / Conference Contribution

Using linear mixed models to compare a self-assessed frailty score with clinician assessed scores in patients approaching major surgery. Presented at International Workshop on Statistical Modelling, Durham

Frailty is a syndrome of reduced physiological and cognitive reserve resulting in vulnerability to physiological insult and delayed recovery. It is a recog-nised predictor of poor perioperative outcomes. The Rockwood clinical frailty score (CFS) is a...

The modelling of count data in real world scenarios often requires models that address over-dispersion. Within the generalized linear modeling framework, various over-dispersion models are available as extensions of the basic Poisson model. Graphical...

Basu, T., Troffaes, M. C. M., & Einbeck, J. (2023, September). A Robust Bayesian Approach for Causal Inference Problems. Presented at ECSQARU 2023, Arras, France

Causal inference concerns finding the treatment effect on subjects along with causal links between the variables and the outcome. However, the underlying heterogeneity between subjects makes the problem practically unsolvable. Additionally, we often... Read More about A Robust Bayesian Approach for Causal Inference Problems.
