Hello
I am running a project but I encounter a problem . I would be happy
to  receive help :
problem:
 I have a binary dependent variable and some covariates logit(y)=a+bx+cz .
I   want to estimate the score vectors and their covariance by the usage of
   logit function and so glm in R .The vlaue of one of the coefficient (
like  b) is known previously and I want to extract a and c and covariance
matrix.
   How could I do it?

Thanks;
