Thanks for your response, that does work, however, it is still not quite

want. I would like to tell betareg what the mean is (in my case, 0.5) and
force it to use that value. Is this possible?
AFAIK package betareg currently does not allow you to fix the mean and only
estimate the precision parameters.
That is also my impression. When I wrote the code, I had in mind that
there should be at least one parameter to estimate in each of the
components (mean/precision). I'll have a look if that can be changed
easily.
