confidence intervals in proc surveyreg

bwise — Thu, 19 Jun 2014 00:16:49 GMT

One recommendation was to add /clb at the end of the variables in the model statement. SAS really didn't like that; it wouldn't even run the model. Then I tried another suggestion which was ALPHA = .05 after the proc statement. The model ran, but the output still did not include confidence intervals. Any other ideas?

From the documentation:

SAS/STAT(R) 9.22 User's Guide

CLPARM

requests confidence limits for the parameter estimates. The SURVEYREG procedure determines the confidence coefficient by using the ALPHA= option, which by default equals 0.05 and produces 95% confidence bounds. The CLPARM option also requests confidence limits for all the estimable linear functions of regression parameters in the ESTIMATE statements.

Note that when there is a CLASS statement, you need to use the SOLUTION option with the CLPARM option to obtain the parameter estimates and their confidence limits.

Thank you, that worked!
