An implementation of the National Information Platforms for
Nutrition or NiPN's analytic methods for assessing quality of anthropometric
datasets that include measurements of weight, height or length, middle upper
arm circumference, sex and age. The focus is on anthropometric status but
many of the presented methods could be applied to other variables.
