Contrast-Aware Annotation for Statistical Graphics: The ggtwotone Package for ggplot2
Beenu Sareena, Heike Hofmann
Readable annotations are essential for interpreting statistical graphics, yet conventional single-color lines and labels can lose visibility when they cross backgrounds with hetero…
Hierarchical Decision Ensembles- An inferential framework for uncertain Human-AI collaboration in forensic examinations
Ganesh Krishnan, Heike Hofmann
Forensic examination of evidence like firearms and toolmarks, traditionally involves a visual and therefore subjective assessment of similarity of two questioned items. Statistical…
A grammar of graphics framework for generalized parallel coordinate plots
Yawei Ge, Heike Hofmann
Parallel coordinate plots (PCP) are a useful tool in exploratory data analysis of high-dimensional numerical data. The use of PCPs is limited when working with categorical variable…
Automatic Matching of Bullet Land Impressions
Eric Hare, Heike Hofmann, Alicia Carriquiry
In 2009, the National Academy of Sciences published a report questioning the scientific validity of many forensic methods including firearm examination. Firearm examination is a fo…
Variations of Q-Q Plots -- The Power of our Eyes!
Adam Loy, Lendie Follett, Heike Hofmann
In statistical modeling we strive to specify models that resemble data collected in studies or observed from processes. Consequently, distributional specification and parameter est…
Model Choice and Diagnostics for Linear Mixed-Effects Models Using Statistics on Street Corners
Adam Loy, Heike Hofmann, Dianne Cook
The complexity of linear mixed-effects (LME) models means that traditional diagnostics are rendered less effective. This is due to a breakdown of asymptotic results, boundary issue…
Enabling Interactivity on Displays of Multivariate Time Series and Longitudinal Data
Xiaoyue Cheng, Dianne Cook, Heike Hofmann
Temporal data is information measured in the context of time. This contextual structure provides components that need to be explored to understand the data and that can form the ba…
Reactive Programming for Interactive Graphics
Yihui Xie, Heike Hofmann, Xiaoyue Cheng
One of the big challenges of developing interactive statistical applications is the management of the data pipeline, which controls transformations from data to plot. The user's in…
Human Factors Influencing Visual Statistical Inference
Mahbubul Majumder, Heike Hofmann, Dianne Cook
Visual statistical inference is a way to determine significance of patterns found while exploring data. It is dependent on the evaluation of a lineup, of a data plot among a sample…
Utilizing Distance Metrics on Lineups to Examine What People Read From Data Plots
Niladri Roy Chowdhury, Dianne Cook, Heike Hofmann +2
Graphics play a crucial role in statistical analysis and data mining. This paper describes metrics developed to assist the use of lineups for making inferential statements. Lineups…
An algorithm for deciding the number of clusters and validation using simulated data with application to exploring crop population structure
Mark A. Newell, Dianne Cook, Heike Hofmann +1
A first step in exploring population structure in crop plants and other organisms is to define the number of subpopulations that exist for a given data set. The genetic marker data…
