The SURVEYREG Procedure

ODS Table Names

PROC SURVEYREG assigns a name to each table it creates; these names are listed in Table 90.8. You can use these names to refer to tables when you use the Output Delivery System (ODS) to select tables and create output data sets. For more information about ODS, see Chapter 20, Using the Output Delivery System.

To improve the consistency among procedures, tables that are generated by the ESTIMATE statements are changed slightly in appearance and formatting compared to releases prior to SAS/STAT 9.22. However, the statistics in the "Estimates" table remain unchanged. The "Coef" table replaces the previous "EstimateCoef" table that displays the $\text{[math]}$ matrix coefficients of an estimable function of the parameters.

The EFFECT, ESTIMATE, LSMEANS, LSMESTIMATE, and SLICE statements also create tables, which are not listed in Table 90.8. For information about these tables, see the corresponding sections of Chapter 19, Shared Concepts and Topics.

ParameterEstimates	Estimated regression coefficients	MODEL	SOLUTION
StrataInfo	Stratum information	STRATA	LIST
VarianceEstimation	Variance estimation	PROC	Default
XPX	$\text{[math]}$ matrix	MODEL	XPX

By referring to the names of such tables, you can use the ODS OUTPUT statement to place one or more of these tables in output data sets.

For example, the following statements create an output data set MyStrata, which contains the "StrataInfo" table, an output data set MyParmEst, which contains the "ParameterEstimates" table, and an output data set Cov, which contains the "CovB" table for the ice cream study discussed in the section Stratified Sampling:

title1 'Ice Cream Spending Analysis';
title2 'Stratified Sample Design';
proc surveyreg data=IceCream total=StudentTotals;
   strata Grade /list; 
   class Kids;
   model Spending = Income Kids / solution covb;
   weight Weight;
   ods output StrataInfo = MyStrata
              ParameterEstimates = MyParmEst 
              CovB = Cov;
run;

Note that the option CovB is specified in the MODEL statement in order to produce the covariance matrix table.
