Hello DHS users,
I need help. When I run my Multivariable model, I get the error message "Note: Missing standard errors because of stratum with single sampling unit." I suspected it was because of how I declared the dataset Survey design to STATA. I am using the Kenya Dataset for 2022. Below are the three different options I used to declare the survey design but none of them seemed to resolve the error. What can I do different? Thank you

Option 1
gen wt=v005/1000000 //generating the weighting variable
egen strata=group(v024 v025) //generating the stratifying variable
svyset [pw=wt], psu(v001) strata(strata) //declaring the survey design

Option 2
gen wt=v005/1000000 //generating the weighting variable
egen strata=group(v024 v025) //generating the stratifying variable
svyset [pw=wt], psu(v021) strata(strata) //declaring the survey design

Option 3
gen wt=v005/1000000 //generating the weighting variable
svyset [pw=wt], psu(v021) strata(v023) //declaring the survey design

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

Enter "help svyset" and look at the last option under "SE".

All three versions of svyset should work, except that you need to insert "singleunit(centered)" right after the "strata" specification.
