  "Description": "The D-score summarizes a child's performance on\ndevelopmental milestones into a single number. Its key feature\nis its generic nature. The method does not depend on a specific\nmeasurement instrument. The statistical method underlying the\nD-score is described in van Buuren et al. (2025)\n<doi:10.1177/01650254241294033>. This package implements model\nkeys to convert milestone scores to D-scores; maps\ninstrument-specific item names to a generic 9-position naming\nconvention; computes D-scores and their precision from a\nchild's milestone scores; and converts D-scores to\nDevelopment-for-Age Z-scores (DAZ) using age-conditional\nreference standards.",
