standard error of exp(coef) from coxph
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

Hi Martin,
It is really a 'PATH' problem. After adding C:\Program
Files\Graphviz2.20\bin to the 'PATH' environment variable, the
Rgraphviz package can be loaded without any error messages.
Sorry that I ONLY set my 'PATH' environment variable correctly
for R but not for Graphviz.
Thank you and Duncan so much for your great help.
