R help - Feb 2010 - restricting coefficient value

Dear colleges,

I am traying to restrict the value of one coefficient in my glm model, see
example:

medparmodel <- glm(los ~ white * (-0.21) + type2 + type3 + hmo,
family=poisson(), data=medpar)

but this does not work, and searching in other help webpages I did not manage to
get any good hint.

Thanks in advance
Rosario

have a look at ?offset().


I hope it helps.

Best,
Dimitris
