Returns confidence intervals from an object of class logitr.
# S3 method for logitr
confint(object, parm, level = 0.95, ...)is an object of class logitr (a model estimated using
the 'logitr()` function).
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.
The confidence level required.
further arguments.
