Confidence intervals for the regression coefficients

Usage

# S3 method for bellreg
confint(object, parm = NULL, level = 0.95, ...)

Arguments

object: an object of the class bellreg
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
...: further arguments passed to or from other methods

Value

A matrix (or vector) with columns giving lower and upper confidence limits for each parameter. These will be labelled as (1-level)/2 and 1 - (1-level)/2 in \

Examples

# \donttest{
data(faults)
fit <- bellreg(nf ~ lroll, data = faults)
confint(fit)

#> (Intercept) 0.3341625182 1.636340171
#> lroll       0.0009488836 0.002869783
