Hello everyone, 
 
I'm running a Stata code for frailty survival model (multilevel hazard analysis) using 2018 Nigeria Demographic and Health Survey Data. 
 
I wrote the design code using the guide provided on this forum: 
svyset v021, weight(wt2_1) strata(v022) , singleunit(centered) || _n, weight(wt1_1) 
 
But when I applied the weight in the code below, it returned an error message that 'option shared() was not allowed with the svy prefix' 
svy: stcox i.w_quintile elect i.anc i.v024 v025 poverty_prop sec_edu_prop, efron shared(v021) || v021: 
 
 
Please how do I apply weight when running a multilevel hazard analysis using Cox regression? 
 
Thank you.
