Hello all,

I am using a glm() and would like to fix one of the regression coefficients
to be a particular value and see what happens to the fit of the model. E.g.:

mod1 <- glm(Y ~ X1 + X2,family='binomial')
mod2 <- glm(Y~[fixed to 1.3]X1 + X2,family='binomial')

The beta for X1 is freely estimated in mod1 but is constrained to be 1.3 in
mod2. Is there a way to do this?

Thank you in advance,

JJ
