The STDRATE Procedure

Applicable Confidence Limits for Rate and Risk Statistics

In the STDRATE procedure, the METHOD= option specifies the standardization method, and the STAT= option specifies either either rate or risk for standardization. Table 95.4 lists applicable confidence limits for different methods with standardized rate, rate SMR, standardized risk, and risk SMR.
