The STDRATE Procedure

Applicable Data Sets and Required Variables for Method Specifications

The METHOD= and DATA= options are required in the STDRATE procedure. The METHOD= option specifies the standardization method, and the DATA= and REFDATA= options specify the study populations and reference population, respectively. You can use the GROUP= option in the POPULATION statement to identify various study populations. Table 88.2 lists applicable data sets for each method.

Table 88.2: Applicable Data Sets for Method Specifications

	Number of Populations
METHOD=	in DATA= Data Set	REFDATA= Data Set
DIRECT	1	X
	2	X
MH	2
INDIRECT	1	X

Table 88.3 lists the required variables for each method.

Table 88.3: Required Variables for Method Specifications

		DATA= Data Set			REFDATA= Data Set
METHOD=	STAT=	RATE	RISK	TOTAL	RATE	RISK	TOTAL
DIRECT	RATE	X					X
	RISK		X				X
MH	RATE	X		X
	RISK		X	X
INDIRECT	RATE			X	X
	RISK			X		X

The symbol “X” indicates that the variable is either explicitly specified or implicitly available from other variables. For example, when STAT=RATE, the variable RATE is available if the corresponding variables EVENT and TOTAL are specified.
