https://communities.sas.com/t5/SAS-Procedures/alpha-values-in-PROC-MIXED/m-p/51295#M14067 Did you set the alpha level in the PROC MIXED statement or in the LSMEANS statement? You can set it in both places.

But after running the program I alwayes get results at 5% significance lavel. It's kind of strange. I changed the alpha values saveral times but still it is producing results at alpha level 5%. Does anyone know what is going on behind it?<BR /> Thanks<BR /> Ahmed Thu, 02 Oct 2008 18:26:14 GMT https://communities.sas.com/t5/SAS-Procedures/alpha-values-in-PROC-MIXED/m-p/51294#M14066 Ahmed_ratan 2008-10-02T18:26:14Z https://communities.sas.com/t5/SAS-Procedures/alpha-values-in-PROC-MIXED/m-p/51295#M14067 Did you set the alpha level in the PROC MIXED statement or in the LSMEANS statement?
