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 % (by default 2.5% and 97.5%).
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.
...
additional argument(s) for methods.
Details
confint is a generic function. Confidence intervals associated to lad
objects are asymptotic, and needs suitable coef and vcov
methods to be available.
