Calculation of Sampling Errors
MICS3 Regional Workshop on Data Archiving and Dissemination
Alexandria, Egypt3-7 March, 2007
Background
The sample selected in a survey is one of the many samples that could have been selected (with same design and size).
Sampling errors are measures of the variability between all possible samples, which can be estimated from survey results.
Background
Calculation of sampling errors is very important;
-Provides information on the reliability of your results
-Tells you the ranges within which your estimates most probably fall
- Provides clues as to the sample sizes (and designs) to be selected in forthcoming surveys
Background
MICS3 sample designs are complex designs, usually based on stratified, multi-stage, cluster samples.
It is not possible to use straightforward formulae for the calculation of sampling errors. Sophisticated approaches have to be used.
New versions of SPSS (13 or 14) are used for this purpose.
SPSS uses Taylor linearization method of variance estimation for survey estimates that are means or proportions.
This approach is used by most other package programs: Wesvar, Sudaan, Systat, EpiInfo, SAS
Background
In MICS3, the objective is to calculate sampling errors for a selection of variables, for the national sample, as well as selected sub-populations, such as urban and rural areas, and regions
Sampling errors will be presented as part of the final report, in Appendix C

Indicate the ranges within which the estimate would fall in 95 percent of all possible samples of identical design and size
Calculating Sampling Errors
Customize all syntax – SE01, SE02 and SE03. Remember to copy your customized “CHRECVAC.sps” syntax into the same directory.
Run “SE01 Sampling Error Calculation.sps”.
This calls “SE02 Strata Pairs.sps”, which pairs clusters and creates pseudo-strata, necessary for these calculations
SE01 calls SE03 also, and calculates sampling errors for the variables in SE03.
The model syntax includes calculations for national, urban and rural areas, and 5 regions.
How SPSS works
COMPLEX SAMPLES module
Can be used to select a sample, or indicate the design of the sample from which the data set comes, so that sampling error estimates can be calculated
Calculations can be done for means and proportions, ratios, frequencies and crosstabs. Also possible to use general linear models and logistic regression by taking complex designs into account.
How SPSS works
Prepare an analysis file to indicate the parameters that define the sample design.CSPLAN ANALYSIS /PLAN FILE='micsplan.csplan' /PLANVARS ANALYSISWEIGHT=hhweight /PRINT PLAN /DESIGN STRATA= strat CLUSTER= HH1 /ESTIMATOR TYPE=WR.
Using the plan file, calculate sampling errors.CSDESCRIPTIVES /PLAN FILE = 'micsplan.csplan' /SUMMARY VARIABLES =treated iodized /MEAN /STATISTICS SE CV COUNT DEFF DEFFSQRT /MISSING SCOPE = ANALYSIS CLASSMISSING = EXCLUDE.

SPSS cannot handle normalized weights – requires the weight variable to be always above 1.
We therefore multiply the sample weight variable with 1,000,000 to enable calculations.
This is later “corrected” in the excel template
Using the Excel template
Copy all values from the SPSS output to the Excel template
Confidence limits are automatically calculated
Copy values on the last column (“Weighted count” in red) onto the “Weighted Count” column, by using “Copy – Paste Special – Values”. This returns the weighted counts back to normal (divides by 1,000,000)
Delete the last column
NOTE: When copying values from the SPSS output to the Excel template, do not copy first to word, and then to excel. This truncates values and you obtain incorrect values in the template. Copy directly from SPSS to Excel

If the value of the indicator is 0.000 or 1.000, then you should complete the row as follows
If the value is based on less than 50 unweighted cases, suppress all values for that indicator, with the exception of the unweighted and weighted counts
