fixed-effect class variables Explanation: It looks like 'treatment', 'trial site', 'visit week', etc. are the input terms for the class variables. 'For Proc Mixed we need to specify that group, time, and subject are class variables. (See the syntax above.) This will cause SAS to treat them as factors (nominal or ordinal variables) instead of as continuous variables.' http://www.uvm.edu/~dhowell/StatPages/More_Stuff/Mixed-Model... 'A fixed-effect class variable for study year was included as a covariate in the health model' http://europepmc.org/articles/PMC4104685 'Si was a fixed effect class variable for study (experiment), Tj was a fixed effect class variable for treatment, Bik was a random class variable for study site (block)' https://academic.oup.com/forestry/article/82/5/583/617194/Ev... -------------------------------------------------- Note added at 22 hrs (2017-09-10 16:45:20 GMT) -------------------------------------------------- Edit: 'Treatment', 'trial site' and 'visit week' correspond to fixed-effect class variables. 'Treatment by visit week' corresponds to an interaction term. |
