Hello,

I want to fit a mixed proportional odds model...
My categorical response has 3 levels...
I have 2 factorial factors (with 2 levels) as independent variables...
My independent variables are random (subject-specific)...

How do i code my independent factors??
Dummy coding (0-1) or (-1,1)???
Can i treat my intercept as fixed??

Thanks in advance...
