Hello members,
I am working on Ghana DHS.
I need your help om two issues:
1. i can see that there is a file that contains child height for age and weight for age according to who. And, the data contain values like -100, -255 etc. And, i know z=scores are in decimal points. so, do i have to divide it by 100 to get that?
2. there is a new who standard, and i use DHS data collected in 1990s and 1980s. how can i compare the data that is collected before with the data that uses the new who standard?
best,
