milestones

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

datasets

The D-score is a quantitative measure of child development.
The D-score follows the Rasch model. See Jacobusse, van Buuren and
Verkerk (2006) <doi:10.1002/sim.2351>. The user can convert
milestone scores from 19 assessment instruments into the D-score
and the DAZ (D-score adjusted for age). Several tools assist in
mapping milestone names into the 9-position Global Scale of Early
Development (GSED) convention. Supports calculation of the D-score
using 'dutch' <doi:10.1177/0962280212473300>,
'gcdg' <doi:10.1136/bmjgh-2019-001724> and 'gsed' conversion keys.
The user can calculate DAZ using 'dutch' and 'gcdg' age-conditional
references.
