Computes confidence intervals for one or more parameters in a fitted model. This a method for objects inheriting from class "lmodel2".
Usage
# S3 method for lmodel2
confint(object, parm, level = 0.95, method = "MA", ...)
Arguments
- object
a fitted model object.
- parm
a specification of which parameters are to be given confidence intervals, either a vector of numbers or a vector of names. If missing, all parameters are considered.
- level
the confidence level required. Currently only 0.95 accepted.
- method
character One of the methods available in
object
.- ...
ignored by this method.
Details
Function lmodel2()
from package 'lmodel2' returns a fitted
model object of class "lmodel2"
which differs from that returned by
lm()
. Here we implement a confint()
method for objects of
this class. It differs from the generic method and that for lm objects in
having an additional formal parameter method
that must be used to
select estimates based on which of the methods supported by
lmodel2()
are to be extracted. The returned object is identical in
its structure to that returned by confint.lm()
.
