Thanks Stas Kolenikov.
As per Stas Kolenikov's advice I have added labels, summary statistics
of the relevant vars.
Hi, I am using the following commands to set up DHS (Demographic and
Health Survey data) data for analysis
gen psu = v021
gen strata = v022
gen sampwt = v005/1000000 //as per DHS instruction//
svyset psu [pw = sampwt], strata(strata)
Where,
v005 sample weight
v021 primary sampling unit
v022 sample stratum number
. sum v005 v021 v022
Variable | Obs Mean Std. Dev. Min Max
-------------+--------------------------------------------------------
v005 | 11440 1000000 479282.7 55728 2707592
v021 | 11440 223.3237 163.2414 1 550
v022 | 11440 89.80385 51.64129 1 177
I have two questions:
1. Is this the right way to set up data ?
2. For the data set I am using, for one year, var V022 is missing.
What other var(s) can I consider to use instead of V022
