Confidence intervals for the regression coefficients

Usage

# S3 method for class 'zibellreg'
confint(object, parm = NULL, level = 0.95, ...)

Arguments

object: an object of the class zibellreg
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

100(1-alpha)% confidence intervals for the regression coefficients

Examples

# \donttest{
data(cells)
fit <- zibellreg(cells ~ smoker+gender|smoker+gender, data = cells, approach = "mle")
