rasch_model_children

Run the multigroup and anchored Rasch Model

The Model Disability Survey (MDS) <https://www.who.int/activities/collection-of-data-on-disability> is a World Health Organization (WHO) general population survey
instrument to assess the distribution of disability within a country or
region, grounded in the International Classification of Functioning,
Disability and Health <https://www.who.int/standards/classifications/international-classification-of-functioning-disability-and-health>. This package provides fit-for-purpose functions
for calculating and presenting the results from this survey, as used by
the WHO. The package primarily provides functions for implementing
Rasch Analysis (see Andrich (2011) <doi:10.1586/erp.11.59>) to
calculate a metric scale for disability.
