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.

Value

A data frame with two rows and three columns.

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().
