Description: 
    The D-score summarizes a child's performance on developmental milestones
    into a single number. Its key feature is its generic nature. The method
    does not depend on a specific measurement instrument. The statistical
    method underlying the D-score is described in van Buuren et al. (2025)
    <doi:10.1177/01650254241294033>. This package implements model keys to
    convert milestone scores to D-scores; maps instrument-specific item names
    to a generic 9-position naming convention; computes D-scores and their
    precision from a child's milestone scores; and converts D-scores to
    Development-for-Age Z-scores (DAZ) using age-conditional reference
    standards.
