![]() Calculating z-score for each of the three anthropometric indices for a single childįor this example, we will use the getWGS() function and apply it toĭummy data of a 52 month old male child with a weight of 14.6 kg ForĬurrent and new users, it is recommended to use addWGSR() and Weight-for-age, height-for-age and weight-for-height still workīut will be removed (defunct) in the next version of zscorer. To maintain support for earlier versions of the package, the earlierįunctions used to calculate anthropometric z-scores for ![]() We can see this error behaviour using the example data: SecondPart is out of range for specified index ThirdPart is not numeric when index = "bfa" Set standing to 3 (unknown) and apply appropriate height or age rules. Missing or nonsense value in standing parameter If anĮrror is encountered in a record then the value NA is returned.Įrror conditions are listed in the table below. Something very wrong with the data or the specified parameters. The addWGSR() function will not produce error messages unless there is These rules are described in the table below. If this is not specified, and in some specialĬircumstances, height and age rules will be applied when calculating The standing parameter specifies how “stature” (i.e. length or Growth References data and the MUAC-for-age reference data.
