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
An optional numeric value to specify the confidence level
required. By default, the value is 0.95, which produces 95% confidence
intervals.

Details
Under regularity condition (Shao 2003, Theorem 4.16 and Theorem 4.17, page
287, 290), the approximate confidence intervals are constructed loosely
based on Fisher information matrix and estimates of coefficients.
