### Ratio Analysis

The "Ratio Analysis" table displays statistics for all the ratios that you request in the RATIO statement. If you do not specify any *statistic-keywords* in the PROC SURVEYMEANS statement, then by default this table displays the ratios and standard errors. The "Ratio Analysis" table can contain the following information for each ratio, depending on which *statistic-keywords* you request:

Numerator, which identifies the numerator variable of the ratio

Denominator, which identifies the denominator variable of the ratio

N, which is the number of observations used in the ratio analysis

number of Clusters

Sum of Weights

DF, which is the degrees of freedom for the test

Ratio

Std Err of Ratio, which is the standard error of the ratio

Var, which is the variance of the ratio

Value, for testing

Pr , which is the two-sided -value for the test

% CL for Ratio, which are two-sided confidence limits for the Ratio

Upper % CL for Ratio, which are one-sided upper confidence limits for the Ratio

Lower % CL for Ratio, which are one-sided lower confidence limits for the Ratio

When you use the ODS OUTPUT statement to create an output data set, if you use labels for your RATIO statement, these labels are saved in the variable Ratio Statement in the output data set.
