D-score for child development
Description
The dscore package implements tools needed to calculate the D-score,
a numerical score that summarizes early development in children by
one number, the D-score.
User functions
The available functions are:
Function Description
get_itemnames() Extract item names from an itemtable
order_itemnames() Order item names
sort_itemnames() Sort item names
decompose_itemnames() Get four components from itemname
get_itemtable() Get a subset from the itemtable
get_labels() Get labels for items
rename_gcdg_gsed() Rename gcdg into gsed lexicon
dscore() Estimate D-score and DAZ
dscore_posterior() Calculate full posterior of D-score
get_tau() Get difficulty parameters from item bank
daz() Transform to age-adjusted standardized D-score
zad() Inverse of daz()
get_reference() Get D-score reference tables
get_age_equivalent() Translate difficulty to age
Built-in data
The package contains the following built-in data:
Data Description
builtin_keys() Available keys for calculating the D-score
builtin_itembank() Collection of items fitting the Rasch model
builtin_itemtable() Collection of items from instruments measuring early child development
builtin_references() Collection of age-conditional reference distributions
milestones() Dataset with PASS/FAIL responses for 27 preterms
gsample Sample of 10 children from the GSED Phase 1 study, gsed lexicon
sample_sf Sample of 10 children from GSED Short Form (GSED-SF)
sample_lf Sample of 10 children from GSED Long Form (GSED-LF)
sample_hf Sample of 10 children from GSED Household Form (GSED-HF)
