You can use the Output Delivery System (ODS) to create a SAS data set from any piece of PROC SURVEYREG output. See the section ODS Table Names for more information. For a more detailed description of using ODS, see Chapter 20: Using the Output Delivery System.
PROC SURVEYREG also provides an OUTPUT statement to create a data set that contains estimated linear predictors and their standard error estimates, the residuals from the linear regression, and the confidence limits for the predictors.
If you use BRR or jackknife variance estimation, PROC SURVEYREG provides an output data set that stores the replicate weights and an output data set that stores the jackknife coefficients for jackknife variance estimation.
