The q–q Boxplot
Boxplots have become an extremely popular display of distribution summaries for collections of data, especially when we need to visualize summaries for several collections simultaneously. The whiskers in the boxplot
A Study in Reproducibility: The Congruent Matching Cells Algorithm and cmcR Package
Scientific research is driven by our ability to use methods, procedures, and materials from previous studies and further research by adding to it. As the need for computationally-intensive methods to
Forensic Science in Legal Education
In criminal cases, forensic science reports and expert testimony play an increasingly important role in adjudication. More states now follow a federal reliability standard, following Daubert v. Merrell Dow Pharmaceuticals
The Contribution of Forensic and Expert Evidence to DNA Exoneration Cases: An Interim Report
This report is from Simon A. Cole, Vanessa Meterko, Sarah Chu, Glinda Cooper, Jessica Weinstock Paredes, Maurice Possley, and Ken Otterbourg (2022), The Contribution of Forensic and Expert Evidence to
How Minutiae Frequency is Perceived and Used by Fingerprint Analysts in the Evaluation of Fingerprint Evidence
Analysts consider the appearance, placement, and number of features within a fingerprint pattern (called minutiae) that correspond when deciding whether two fingerprints originated from the same person. Little is known
Likelihood ratios for categorical count data with applications in digital forensics
We consider the forensic context in which the goal is to assess whether two sets of observed data came from the same source or from different sources. In particular, we

Reliability for Binary and Ordinal Data in Forensics
Black-box studies are a crucial part of assessing the accuracy and reliability of subjective decisions in forensics. The extant black-box studies have generally had two components. In the first study,
Uncertainty in probabilistic genotyping of low template DNA: A case study comparing STRMix™ and TrueAllele™
Two probabilistic genotyping (PG) programs, STRMix™ and TrueAllele™, were used to assess the strength of the same item of DNA evidence in a federal criminal case, with strikingly different results.
