Changes in version 1.1.2 - Added join_records() to join files after the MEC record linkage procedure. Changes in version 1.1.1 (2026-05-21) - Improved mec_blocking() by using inverted unsupervised MEC. - Added alpha in mec_blocking() for controlling the FLR-MMR trade-off. Changes in version 1.1.0 (2026-05-08) - Added mec_blocking() for blocked unsupervised MEC with pooled training and blockwise prediction using the blocking package. - Added support for creating comparison vectors on a supplied table of record pairs through the pairs argument in comparison_vectors(). - Added census and cis example datasets for larger record linkage examples. - Added a vignette showing MEC with blocking on the cis and census datasets. - Added optional progress messages via the verbose argument in mec(), train_rec_lin(), predict.rec_lin_model(), and mec_blocking(). - Improved validation of supplied match and pair tables, including clearer checks for row indices, duplicate pairs, missing values, and non-finite comparison values. - Improved print methods for linkage results, including consistent percentage formatting for error rates. Changes in version 1.0.1 (2025-12-13) - Fixed CRAN errors. Changes in version 1.0.0 (2025-11-18) - Implemented comparison functions abs_distance() and jarowinkler_complement(). - Added support for comparing two datasets using comparison functions. - Added support for training a supervised record linkage model using probability or density ratio estimation, based on the following methods: "binary", "continuous_parametric", and "continuous_nonparametric". - Added support for creating a supervised record linkage model using a custom machine learning (ML) classifier. - Added support for predicting matches based on a record linkage model. - Added the unsupervised maximum entropy classification (MEC) algorithm for record linkage. Supported methods are: "binary", "continuous_parametric", "continuous_nonparametric", and "hit_miss". - Added support for creating the predicted set of matches based on: its estimated size, a target false link rate (FLR) or a target missing match rate (MMR). - Implemented S3 methods for printing. - Added support for evaluation when true matches are known. - Added documentation and examples.
