This package implements the statistical\nmethod described by Madeline Johnson and Danica Ommen (2021)\n<doi:10.1002/sam.11566>. Similarity measures and a random\nforest produce a score-based likelihood ratio that quantifies\nthe strength of the evidence in favor of the documents being\nwritten by the same writer or different writers.",
