I had previously tried the “solution” option in the model statement but it did not work. I may have had an extra / in there. It seems to be working now though <span class="lia-unicode-emoji" title=":slightly_smiling_face:">🙂</span> Sat, 19 May 2018 02:53:35 GMT https://communities.sas.com/t5/Statistical-Procedures/How-to-get-fixed-effects-estimates-glimmix-poisson/m-p/463480#M24151 rfriesdo 2018-05-19T02:53:35Z
