Hi, I have a question about how to extract paramters from a fitted model. I can extract coefficients and std, but from some other statistics, I dont know how to extract. Can anyone help?

Here it is an example:

> coxout<-coxph(Surv(t,t.censor)~x)

> coxout

Call:
coxph(formula = Surv(t, t.censor) ~ x)

coef exp(coef) se(coef) z p
x 0.349 1.42 0.257 1.36 0.17

Likelihood ratio test=1.84 on 1 df, p=0.175 n= 200

> coxout$coef

        x
0.3490500

> coxout$p

NULL Any convienent way to extract the LRT and the p value? thank you!
