Hi,
I wish to calculate proportion of stunted children for the micro-level administrative units like district and sub-districts with their standard errors. I followed the usual method of complex survey method in SPSS. The problem I found that for the sub-population having single cluster the design effect is zero and also the standard error is zero. The SPSS plan code is given below.


COMPUTE WGT=V005/1000000.
EXECUTE .

* Analysis Preparation Wizard.
CSPLAN ANALYSIS
/PLAN FILE='C:\Users\dell\Downloads\BDHS2011.csaplan'
/PLANVARS ANALYSISWEIGHT=WGT
/SRSESTIMATOR TYPE=WR
/PRINT PLAN
/DESIGN STRATA=V023 CLUSTER=V001
/ESTIMATOR TYPE=WR.


May be I need the exact way for obtaining the standard error. If I avoid the sample design and use sampling weight only, I obtain the same estimates as I found using sampple design but the standard error is not now zero. Thus the issue is the design effect for the small sub-population. Is there any way to avoid such computation problem.

If I am working correctly and the results are theoretically reasonable, can you please inform me the exact reasons.

If there is any other technique, please suggest e hw can I solve the problem.

Regards,
Sumonkanti Das

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


This is an SPSS question, not a DHS question, and almost no one at DHS uses SPSS. If you were using Stata, the syntax would be much simpler and you could use the "singleunit()" option, which has been described earlier on the forum. I have no idea what you would do in SPSS.
