[R] How to keep a coefficient fixed when using rq {quantreg}?
Hello all, I would like to compute a quantile regression using rq (from the quantreg package), while keeping one of the coefficients fixed. Is it possible to set an offset for rq in quantreg? (I wasn't able to make it to work) Thanks, Tal ----------------Contact Details:------------------------------------------------------- Contact me: Tal.Galili at gmail.com |? 972-52-7275845 Read me: www.talgalili.com (Hebrew) | www.biostatistics.co.il (Hebrew) | www.r-statistics.com (English)

Ah yes offsets, I've meant to look into this, but never quite understood why something like: rq((y - xk - bk) ~ x1 + x2) wasn't just as convenient....
