Likelihood Function
Let 
be a link function such that
 |
where 
is a column vector for regression coefficients. The pseudo-log likelihood is
 |
Denote the pseudo-estimator as 
, which is a solution to the estimating equations:
 |
where 
is the matrix of partial derivatives of the link function 
with respect to .
To obtain the pseudo-estimator , the procedure uses iterations with a starting value 
for . See the section Iterative Algorithms for Model Fitting for more details.
