[R-sig-Epi] Calculate local RR from GAM

[Przemysław Jura]

Dear Group,
I am just a beginner in Epidemiology, epi-statistics and this group hence, in advance
I apologize if I ask trivial question.

I would like to ask how is it possible to calculate from GAM (general
additive model) Relative Risk
the model has following formula:
log(E[O_i]) ~ log(N_i) + someCovariates_i, where Oi is number of cases
of some disease in i-th area, N is population at risk in i-th area,
other covariates are i-th region specific.
I one paper authors calculated RR for each i-th region out of this model, but I have no
idea how can I do it myself.



Kindest regards,

pj
