Then use PROC PLM with the TESTVALUE= option on the ESTIMATE statement. The UPPER or LOWER option on the ESTIMATE statement will give you one-tailed tests.&nbsp;</P> Mon, 05 Jun 2023 14:47:08 GMT https://communities.sas.com/t5/Statistical-Procedures/PROC-MIXED-model-How-to-compare-a-coefficient-estimate-to-a/m-p/879257#M43484 StatsMan 2023-06-05T14:47:08Z https://communities.sas.com/t5/Statistical-Procedures/PROC-MIXED-model-How-to-compare-a-coefficient-estimate-to-a/m-p/879696#M43524 Thanks!<BR />Very helpful!
