Description: Facilitates some of the analyses performed in studies of
        behavioral economic discounting. The package supports scoring
        of the 27-Item Monetary Choice Questionnaire (see Kaplan et
        al., 2016; <doi:10.1007/s40614-016-0070-9>), calculating k
        values (Mazur's simple hyperbolic and exponential) using
        nonlinear regression, calculating various Area Under the Curve
        (AUC) measures, plotting regression curves for both
        fit-to-group and two-stage approaches, checking for
        unsystematic discounting (Johnson & Bickel, 2008;
        <doi:10.1037/1064-1297.16.3.264>) and scoring of the minute
        discounting task (see Koffarnus & Bickel, 2014;
        <doi:10.1037/a0035973>) using the Qualtrics 5-trial discounting
        template (see the Qualtrics Minute Discounting User Guide;
        <doi:10.13140/RG.2.2.26495.79527>), which is also available as
        a .qsf file in this package. The package also fits
        mixed-effects (hierarchical) discounting models with a
        scale-location-truncated beta likelihood that admits
        indifference points at exactly 0 and 1 (Kim, Kaplan, Koffarnus,
        and Franck, 2025; <arXiv:2509.13167>).
