Hi,
I'm trying to fit a proportional ordinal logistic model using function
polr() (package MASS).
Is there a way to fix certain betas in the regression (e.g. function
arima() allows this by defining fixed )
Maybe there is another function than polr() which allows that?
See ?offset, the standard tool in regression-like fitting in R (and
described in the book MASS supports).
Thanks
Kazys
