A Dirichlet process model for directional-linear data with application to bloodstain pattern analysis

July 3, 2025 / Publication / Bloodstain, Forensic Statistics

Directional data require specialized models because of the non-Euclidean nature of their domain. When a directional variable is observed jointly with linear variables, modeling their dependence adds an additional layer

Towards a likelihood ratio approach for bloodstain pattern analysis

January 9, 2023 / Publication / Bloodstain, Forensic Statistics

In this work, we explore the application of likelihood ratio as a forensic evidence assessment tool to evaluate the causal mechanism of a bloodstain pattern. It is assumed that there

A Novel, Data-Driven Approach to the Classification of Bloodstain Patterns

March 17, 2022 / Presentation Slides / Bloodstain

Bloodstain pattern analysis is the study of bloodstains at a crime scene with the purpose of drawing inference about the crime. A typical objective for bloodstain pattern analysis is to

Using the Likelihood Ratio in Bloodstain Pattern Analysis

March 17, 2022 / Publication / Bloodstain, Forensic Statistics

There is an apparent paradox that the likelihood ratio (LR) approach is an appropriate measure of the weight of evidence when forensic findings have to be evaluated in court, while
