Hi there,
You forgot to give us some detail, but here is my guess:
install.packages('gee')
require(gee)
# fitting the model as in the help file under ?gee
data(warpbreaks)
fit <- gee(breaks ~ tension, id = wool, data = warpbreaks, corstr =
"exchangeable")
# extracting what you need
summa
I am having some difficulties to locate the standard error from GEE output.
---sample output using list (geemodel)
Link: Identity
Variance to Mean Relation: Gaussian
Correlation Structure: Exchangeable
Call:
gee(formula = days.sick1 ~ bm
2 matches
