Complex Samples Ratios
The Complex Samples Ratios procedure displays univariate summary statistics for ratios of variables. Optionally, you can request statistics by subgroups, defined by one or more categorical variables.
Example. Using the Complex Samples Ratios procedure, you can obtain descriptive statistics for the ratio of current property value to last assessed value, based on the results of a statewide survey carried out according to a complex design and with an appropriate analysis plan for the data.
Statistics. The procedure produces ratio estimates, t tests, standard errors, confidence intervals, coefficients of variation, unweighted counts, population sizes, design effects, and square roots of design effects.
Complex Samples Ratios Data Considerations
Data. Numerators and denominators should be positive-valued scale variables. Subpopulation variables can be string or numeric but should be categorical.
Assumptions. The cases in the data file represent a sample from a complex design that should be analyzed according to the specifications in the file selected in the Complex Samples Plan dialog box.
Obtaining Complex Samples Ratios
This feature requires the Complex Samples option.
- From the menus choose:
- Select a plan file. Optionally, select a custom joint probabilities file.
- Click Continue.
- In the Complex Samples Ratios dialog box, select at least one numerator variable and denominator variable.
Optionally, you can specify variables to define subgroups for which statistics are produced.
