Design effect. The ratio of the variance of the estimate to the variance obtained by assuming
that the sample is a simple random sample. This is a measure of the effect of specifying a
complex design, where values further from 1 indicate greater effects.
Square root of design effect. This is a measure of the effect of specifying a complex design,
where values further from 1 indicate greater effects.
Ttest. You can request t tests of the estimates against a specifi
ed value.

Ratios. This group determines which cases are used in the analysis.
Use all available data. Missing values are determined on a ratio-by-ratio basis. Thus, the cases
used to compute statistics may vary across numerator-denominator pairs.
Ensure consistent case base. Missing values are determined across all variables. Thus, the
cases used to compute statistics are consistent.
Categorical Design Variables. This group determines whether user-missing values are valid
or invalid.
