sample_sf

A demo dataset with developmental scores at the item level for
10 random children from the GSED Phase 1 data.

datasets

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.
