Hello, I run the following commands and did calculated weight for length:
//egen WLZ_WHO=zanthro(weight,wl,WHO), xvar(height) gender(gender) gencode(male=1, fem
> //ale=2) nocutoff
//(Z values generated for 3927 cases)
//(gender was assumed to be coded male=1, female=2)
//(Z values can be missing because xvar is nonpositive or otherwise
//out of range for the chart code, or the gender variable is missing)
//(9257 missing values generated)//
`
using the similar commands how can I further define for children under 2 or above under 2 year old (weight for height).
