Description: Provides PLUS-derived extensions for positive and
        unlabeled (PU) learning from unbalanced cases and sparse
        structures, based on Zhou et al. (2022)
        <doi:10.1371/journal.pcbi.1009956>. Iteratively relabels
        unlabeled observations via penalised logistic regression and
        pseudo-label updates, then refits a final sparse model.
        Includes weighted bootstrap sampling, convergence diagnostics,
        prediction, coefficient extraction, and assessment utilities.
