Dear R users,
Is there a simple way to use the effect function (library(effects)) with
a GEE estimated model?
library(gee)
library(MASS)
library(effects)
attach(epil)
b = gee(y ~ lbase*trt + lage + V4, family=poisson, id=subject,
corstr="exchangeable")
plot(effect("lbase*trt", b))
# Errore in effect("lbase*trt", b) : nessun metodo applicabile per
"effect"
