The classifier\ncomputes a continuous log-likelihood ratio score per document\nand uses a data-driven decision threshold estimated via K-fold\ncross-validation on a user-selected criterion (accuracy, F1\nscore, Matthews correlation coefficient, balanced error, etc.).\nAn optional iterative refinement procedure locally re-estimates\nthe threshold in regions of class overlap using either Gaussian\nkernel density estimation or a Central Limit Theorem bootstrap\napproximation. The package exposes an idiomatic R formula +\ndata.frame interface together with a 'quanteda'-based text\npreprocessing pipeline, supports user-supplied document-feature\nmatrices, and includes an optional word-embedding extension\nthat augments the Bag-of-Words with K nearest semantic\nneighbours of each token. The package additionally implements\nthe p-value extension proposed by Romano (2025) for both\ndocument- and feature-level interpretability via\ntbnb_pvalues().
