Description: Evaluates prediction accuracy for continuous outcomes and the
    predictive performance of survival models in a unified framework.
    Implements the R-squared, L-squared, pseudo R-squared and related explained
    variation measures of Li and Wang (2019)
    <doi:10.1080/01621459.2018.1515079>, the concordance indices of Harrell
    et al. (1982) <doi:10.1001/jama.1982.03320430047030> and Uno et al.
    (2011) <doi:10.1002/sim.4154>, the time-dependent area under the receiver
    operating characteristic curve (AUC) of Heagerty, Lumley and Pepe (2000)
    <doi:10.1111/j.0006-341X.2000.00337.x>, and the Brier score of Graf et
    al. (1999)
    <doi:10.1002/(SICI)1097-0258(19990915/30)18:17/18%3C2529::AID-SIM274%3E3.0.CO;2-5>.
    Supports right-censored data; competing risks, following Wolbers et al.
    (2014) <doi:10.1093/biostatistics/kxt059>, Wu and Li (2018)
    <doi:10.1002/sim.7806> and Zhuang et al. (2025)
    <doi:10.48550/arXiv.2507.15040>; and two-phase sampling designs such as
    case-cohort and nested case-control studies, following Lee,
    Zeleniuch-Jacquotte and Liu (2021) <doi:10.1080/02664763.2020.1861225>.
    Revives and expands the original 'PAmeasures' package with a unified
    interface for survival prediction assessment.
