Package: dscore Type: Package Title: D-Score for Child Development Version: 2.1.0 Authors@R: c(person("Stef", "van Buuren", email = "stef.vanbuuren@tno.nl", role = c("cre", "aut")), person("Iris", "Eekhout", email = "iris.eekhout@tno.nl", role = "aut"), person("Arjan", "Huizing", email = "arjan.huizing@tno.nl", role = "aut"), person("Jonathan", "Seiden", email = "jseiden@g.harvard.edu", role = "aut")) 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) . 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.
