Hello,   I'm trying to force a variable to stay within a stepwise regression.   When I follow the instructions published on "SAS Notes", it only retains that particular variable and no longer goes through the stepwise selection process.   Is there a way to let the program do the selection for me, but make sure to keep that particular variable as one of the selected?   The instructions were as follows: Set the Selection Model property to Backward, Forward, or Stepwise. Set the Use Selection Defaults property to No. Click the Selection Options ... property. A Selection Options window is displayed. In the Force Candidate Effects property, enter the number of variables that you want to force into the model. Click OK to close the Selection Options window. Change the User Terms property to Yes. Click the Term Editor ... property. A Term window is displayed. One at a time, click the variable that you want to force into the model, click the right-arrow button, and click Save. Make sure that the variables that you want to include are listed first. When finished, click OK to close the Term window. Run the node. Thanks. ... View more
