Hi! How are can solve the error of "Missing test statistics because of stratum with single sampling unit." ??

I am using Nigeria DHS 2013 to get crosstabs and associations with chi square and p values.

I tried to follow this, but not able to follow the same for DHS: http://www.stata.com/support/faqs/statistics/stratum-with-on e-psu/

Thanks!!

Following is a response from Senior DHS Stata Specialist, Tom Pullum:

This situation has been described in earlier forum posts. You need to define a stratum variable. You then include the "singleunit()" option in svyset. There are three possibilities for what goes between the parentheses. I have checked and they all give similar results. I usually use "centered". Here are the three possibilities:

svyset v021 [pweight=v005], strata(strata) singleunit(centered)
svyset v021 [pweight=v005], strata(strata) singleunit(scaled)
svyset v021 [pweight=v005], strata(strata) singleunit(certainty)
