Title: Lab for Matrix Completion and Imputation of Discrete Rating Data
Version: 0.1.0
Date: 2025-07-25
Description: Collection of methods for rating matrix completion, which
        is a statistical framework for recommender systems. Another
        relevant application is the imputation of rating-scale survey
        data in the social and behavioral sciences. Note that matrix
        completion and imputation are synonymous terms used in
        different streams of the literature. The main functionality
        implements robust matrix completion for discrete rating-scale
        data with a low-rank constraint on a latent continuous matrix
        (Archimbaud, Alfons, and Wilms (2025)
        <doi:10.48550/arXiv.2412.20802>). In addition, the package
        provides wrapper functions for 'softImpute' (Mazumder, Hastie,
        and Tibshirani, 2010,
        <https://www.jmlr.org/papers/v11/mazumder10a.html>; Hastie,
        Mazumder, Lee, Zadeh, 2015,
        <https://www.jmlr.org/papers/v16/hastie15a.html>) for easy
        tuning of the regularization parameter, as well as benchmark
        methods such as median imputation and mode imputation.
