transform method for class inferencetransform.inference(`_data`, f, f.prime, ...)inference.exp.f in order to compute the standard
error of the transformed point estimates based on the delta method.inference.transform from the base package.It can be used to get the hazard ratio scale in inference objects
created from coxph objects and the odds ratio scale from
logistic regression created from glm
(both using f=exp, f.prime=exp).
