Note: Do not specify the PROC, BY, and RUN statements in this field.The specification is in this form to provide you with maximum power and flexibility to fit various models. The most common statements that you will need are CLASS, MODEL, RANDOM, ESTIMATE, and LSMEANS, but most any valid PROC MIXED/GLIMMIX commands will work.The choice of which PROC to apply depends on the selections specified using the Unbounded Variance Component Estimates, Model Distribution, and Link Function options.Note: Use of this option requires an understanding of SAS syntax. You should refer to the documentation for SAS PROC MIXED or SAS PROC GLIMMIX and/or seek statistical assistance from an experienced SAS programmer.
