Thus neither CI from the MASS library is incorrect, though the profile-likelihood method is thought to be superior, especially for … WebThe package provides a confint method for the fitted value. The method returns both a Wald confidence interval and profile likelihood interval. The Wald interval takes the usual the form where the lower and upper bound are given by \(\hat{s} \pm z^*(1-\alpha/2)\times se(\hat{s}))\).The profile likelihood interval finds the end-points of the interval that …
