Handwriter is designed to assist forensic examiners by analyzing handwritten documents against a closed set of potential writers. It determines the probability that each writer wrote the document. Whether you are a forensic document examiner, legal professional, academic, or simply curious about how statistics are applied to handwriting, handwriter provides an automated way to evaluate handwriting samples.
Handwriter requires R, RStudio IDE, and JAGS.
Install the handwriterApp R package. Open RStudio and navigate to the console window and type
