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 88.4 lists applicable confidence limits for different methods with standardized rate, rate SMR, standardized risk, and risk SMR.

Table 88.4: Applicable Confidence Limits for Standardized Rate and Risk Statistics

		Confidence Limits
Statistic	METHOD=	Normal	Lognormal	Gamma	Poisson
Rate	DIRECT	X	X	X
	MH	X	X	X
	INDIRECT	X	X		X
Rate SMR	INDIRECT	X	X		X
Risk	DIRECT	X	X
	MH	X	X
	INDIRECT	X	X		X
Risk SMR	INDIRECT	X	X		X

Table 88.5 lists applicable confidence limits for stratum-specific rate, rate SMR, risk, and risk SMR.
