Confidence intervals of the coefficients of an lm or glm fit with a given covariance matrix. Equivalent to R's
lmtest::coefci().
The limits estimate ± q se with the t quantile on df degrees of freedom, or the normal quantile (by default for a
glm of every family, as lmtest). parm takes 0-based indices (R: 1-based) or names. The standard errors as in
coeftest: from the covariance in units of powers of 2 for a result of vcovHC or vcovCL or
its original matrix, not for a copy of the matrix (which gives intervals of width 0 where it holds 0).
