search for: x3_i

Dear users, I am trying to show the equation (including coefficients from the model estimates) for a gam model but do not understand how to. Slide 7 from one of the authors presentations (gam-theory.pdf URL: http://people.bath.ac.uk/sw283/mgcv/) shows a general equation log{E(yi )} = ?+ ?xi + f (zi ) . What I would like to do is put my model coefficients and present the equation used. I am an

...exes YEAR, \beta is the vector of fixed effects \eta_i in the random intercept for SITE and \phi_j are the random intercept and coefficient for YEAR. I have written x'_i because the covariates are assumed (reasonably) to be constant over the 5 years. Thus, obviously, the z'_i = (1, x3_i) are constant over j as well. Using lme4 0.8-2 and R 1.9.0 (under Windows), the call GLMM(y~x1 + x2 + x3,random = list(YEAR=~1+x3, SITE=~1), data=foo, family=poisson, offset=log(reps)) seemed to work correctly, so far as I can tell. The fixed effects were more-or-less consistent with those est...
