Dear List,
Must be a silly question, but I was wondering whether there is a direct way of
calculating "standard error of a HR or exp(coef)" from coxph objects
x <- coxph(Surv(time, status) ~ age + inst, lung)> x coef exp(coef)
se(coef) z page 0.0190 1.02 0.00925 2.06 0.04inst -0.0104
0.99 0.01028 -1.01 0.31
cheers,
Ehsan
