The STDRATE Procedure

Graphics Output

This section describes the use of ODS for creating graphics with the STDRATE procedure. To request these graphs, ODS Graphics must be enabled and you must specify the associated graphics options in the PROC STDRATE statement. For more information about ODS Graphics, see Chapter 21: Statistical Graphics Using ODS.

Strata Distribution Plot

The PLOTS=DIST option displays the proportion of exposed time or sample size for each stratum in the populations.

Strata Effect Plot

The PLOTS=EFFECT option displays the stratum-specific effect measure of rate difference, rate ratio, risk difference, or risk ratio. In addition, the crude effect measure and confidence limits of these stratum-specific effect estimates are also displayed.

Strata Rate Plot

The PLOTS=RATE option displays the stratum-specific rate estimates and their confidence limits of populations. In addition, the overall crude rates of populations are also displayed.

Strata Risk Plot

The PLOTS=RISK option displays the stratum-specific risk estimates and their confidence limits of populations. In addition, the overall crude risks of populations are also displayed.

Strata SMR Plot

The PLOTS=SMR option displays the SMR for each stratum in the populations.
