Description: Implements 'PRIDIT' (Principal Component Analysis applied
        to 'RIDITs'), an unsupervised, nonparametric method for
        aggregating ordinal, categorical, and continuous indicators
        into a single interpretable composite score. Originally
        proposed by Brockett et al. (2002)
        <doi:10.1111/1539-6975.00027> for insurance fraud detection and
        extended to hospital quality measurement by Lieberthal (2008)
        <doi:10.1111/j.1475-6773.2007.00821.x> and Lieberthal and Comer
        (2013) <doi:10.1111/rmir.12009>. The package provides: (1)
        low-level functions ridit(), PRIDITweight(), and PRIDITscore();
        (2) a unified pridit() entry point returning a classed object
        with print, summary, 'autoplot', and 'coef' methods; (3)
        pridit_boot() for bootstrap confidence intervals on scores and
        weights; (4) a step_pridit() recipe step for out-of-sample
        scoring within the 'tidymodels' framework; and (5)
        pridit_longitudinal() for panel data, computing cross-period
        stability of scores and weights.
