Hello Dear Experts
I am new to using EDS databases.
I am trying to assess the vaccination status of children from 12 months to 23 months using the Burundi DHS 2016-2017 in order to use it as a covariate. I followed the steps of the STATA code.
However, my results are different from those in the report.
Could you tell me my errors or give an idea.
thank you

*La vaccination concerne les enfants de 12 à 23 mois
*** Two age groups used for reporting.
* choose age group of interest
*
gen agegroup=0
replace agegroup=1 if age_nourrissons>=12 & age_nourrissons<=23

*/

/*
gen agegroup=0
replace agegroup=1 if age>=24 & age<=35
*/

* selecting children
keep if agegroup==1
keep if b5==1
br agegroup age_nourrissons

Following is a response from DHS staff member, Tom Pullum:

Did you get this Stata code from the DHS website, for chapter 10 ( https://github.com/DHSProgram/DHS-Indicators-Stata/blob/mast er/Chap10_CH/CH_VAC.do)? It looks similar but I don't have time to review it in detail. If you use the GitHub code for just part of a chapter, you have to be careful. There is usually some setup for the entire chapter that needs to be run first. Can you try running the entire code for chapter 10? That may produce the correct results. Please let us know if that works.
