Computes confidence intervals for one or more parameters in a model fitted by
coxphw. Objects of this class have methods for the functions summary,
print, coef, vcov, plot, and confint.
# S3 method for coxphw
confint(object, parm, level = 0.95, ...)a fitted model object of class coxphw.
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.
additional argument(s) for methods.
A matrix (or vector) with columns giving lower and upper confidence limits for each parameter. These will be labeled as (1-level)/2 and 1 - (1-level)/2 in % (by default 2.5% and 97.5%).
