This is a confint method for class "stdGee".
# S3 method for stdGee
confint(object, parm, level = 0.95, fun, type="plain", ...)an object of class "stdGee".
not used.
the coverage probability of the confidence intervals.
a function of one vector argument of length p, which returns a scalar.
a string specifying the type of confidence interval; plain
(for untransformed) or log (for log-transformed).
not used.
a matrix with 1 row and 2 columns, containing the computed confidence interval.
confint.stdGee extracts the est element from object, and
inputs this to fun. It then uses the delta method to compute a confidence
interval for the output of fun.
