milestones

<p>A demo dataset with developmental scores at the item level for
a set of 27 preterm children.</p>

datasets

The D-score summarizes the child's performance on a set of
milestones into a single number. The package implements four Rasch model
keys to convert milestone scores into a D-score. It provides tools to
calculate the D-score and its precision from the child's milestone scores,
to convert the D-score into the Development-for-Age Z-score (DAZ)
using age-conditional references, and to map milestone names into a
generic 9-position item naming convention.
