Hi,
I am trying to use the following model formula in gls() in the nlme package:
R ~ Turb + offset(ssb)
Unfortunately, gls() seems to ignore the offset argument and give results
that are identical to
R ~ Turb
This is not the case when I use lm() - however, I would like to include a
corAR1() term as well, which is why I am using gls().
Is this known and intended behaviour? If so, is there a recommended
workaround/alternative?
Best wishes,
Mark
