anthro-js

This is a javascript adaptation of the z-score portion of Dirk Schumacher's anthro library for R. It will supply z-scores for anthropometric measurements based on standards developed by the WHO. For more information on the method, inputs and outputs, see Schumacher's repo or the CRAN documentation.

Function arguments are mirrored as closely as possible, however javascript has no native concept of data frames or NA variables. Thus the anthro_zscore function has been modified to operate only element-wise. It will require a row-wise application if being applied to a table of measurements.

Installation

npm i anthro-js
