Complex Samples Ratios Statistics
Statistics. This group produces statistics associated with the ratio estimate.
- Standard error. The standard error of the estimate.
- Confidence interval. A confidence interval for the estimate, using the specified level.
- Coefficient of variation. The ratio of the standard error of the estimate to the estimate.
- Unweighted count. The number of units used to compute the estimate.
- Population size. The estimated number of units in the population.
- 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.
T test. You can request t tests of the estimates against a specified value.
