Hi
I am a PhD student in economics, I am writing my first paper in the impact of women employment on child nutrition - for Egypt - 2008 and 2014
My outcome variable is child health indicators (HAZ - WHZ - WAZ), I produced binary variables: (stunted wasted overweight underweight)
The main independent variable is women employment , yes/no
Also I have controled for other variables such as child characteristics , mother characteristics, Household characteristics.
In the begging I started using the KR file since the child is my outcome variable.I cleaned the data and started analyzing it, however, when I tried to replicate the tables and analysis for one paper which is published in Q1 journal.
The authors used Egypt 2014 DHS dataset.
The result for the replicating frequancy tables were not the same, so I tried to use the IR file. and then I replicated these tables successfully.
So to confirm, The frequancy tables for maternal employment comes from IR file.
For the OLS, I coudn't replicate their work yet but i got significant coefficient as them.
*******************************************************stata comand ********************************
gen strata=v023
gen psu=v021
gen sampwt=v005/1000000
svyset psu, strata(strata) weight(sampwt) vce(linearized)
gen id = sgov
*****************OLS ************************************************************ ***********
svy: reg stunted maternalemployed ib1.gender bage100 bagesq100 i.twin i.birthsize mage100 magesq100 mothertotedu100 mothertotedusq100 i.marital nofchildern i.wealth nofadult i.id
They stated " We include a governorate dummy to control for regional differences and governorate fixed effect" so I include the i.id ( the governate fixed effect)
**************************************************Result**** **********************************************
They have 12,502 observation , R2= 0.0760 , mother employed coefficient : 0.0316 (10% significant)
for my analysis i got
In the IR - Number of obs = 9,809 R-squared = 0.0825 , mother employed coefficient : ..0336397 (5% significant )
In the BR - Number of obs = 13,415 R-squared = 0.0751 , mother employed coefficient : .0248322 (10% significant )
In the KR - Number of obs = 11,774 R-squared = 0.0751 , mother employed coefficient : -.1192583 (1% significant )
I used the same variables as they used and i did the weighting, strata, cluster , and fixed effect for the governate.
as they stated in their paper
" all the regression analyses have corrected for the survey design, i.e. the sampling weight, the cluster, and the strata were all taken into account."
************************************************************ ********************
My questions here are:
1- - what do you think which file should i go with ? As you can see the cofficient of the Maternal employment in KR file is negative where it's positive in the IR file. the relationship will be different and the conclusion of the paper as well.
2- is it possible to do the Description table from one file ( IR ) and the analysis from another file ( KR )
or the paper should use only one kind of recode file. (IR BR KR)
I appreciate your feedback and assistance.
Thank you
