The GEE Procedure

PROC GEE Statement

PROC GEE <options>;

The PROC GEE statement invokes the GEE procedure. Table 44.1 summarizes the options available in the PROC GEE statement.

Table 44.1: PROC GEE Statement Options

Option	Description
DATA=	Specifies the input data set
DESCENDING	Sorts the response variable in the reverse of the default order
NAMELEN=	Specifies the length of effect names
ORDER=	Specifies the sort order of CLASS variable
PLOTS	Controls the plots that are produced through ODS Graphics

You can specify the following options.

DATA=SAS-data-set

specifies the SAS data set that contains the data to be analyzed. If you omit the DATA= option, PROC GEE uses the most recently created SAS data set.

DESCENDING DESCEND DESC

requests that the levels of the response variable for the binomial model that uses a single-variable response syntax be sorted in the reverse of the default order.

NAMELEN=number

specifies the length to which long effect names are shortened. The default and minimum value is 20.

PLOTS <= plot-request >

controls the plots produced through ODS Graphics. For example:

proc gee plots=histogram;
   model y=x1;
run;

For more information about enabling and disabling ODS Graphics, see the section Enabling and Disabling ODS Graphics in Chapter 21: Statistical Graphics Using ODS.

You can specify the following plot-requests:

ALL: requests that all default plots be produced.
HISTOGRAM: creates a histogram for the predicted weights from the missingness model.
NONE: suppresses all plots.
