Dear all,
I have a question concerning the p-value. When running coxph I get a p-value
= 0. :confused:
Can this be true? Why aren´t there decimal points? Is there a way to find
out the exact p-value?
Here is the output:
----------------------------------------------------------------------------------------------------
Call:
coxph(formula = Surv(start, stop, status) ~ Albumin_gproL, data = dial,
na.action = na.omit, method = "breslow")
n=22449 (31 observations deleted due to missingness)
coef exp(coef) se(coef) z p
Albumin_gproL -0.157 0.855 0.0172 -9.16 0
exp(coef) exp(-coef) lower .95 upper .95
Albumin_gproL 0.855 1.17 0.826 0.884
Rsquare= 0.003 (max possible= 0.033 )
Likelihood ratio test = 73.6 on 1 df, p=0
Wald test = 83.8 on 1 df, p=0
Score (logrank) test = 86.1 on 1 df, p=0
> cox.zph(cox_1111)
rho chisq p
Albumin_gproL -0.0509 0.197 0.657
----------------------------------------------------------------------------------------------------
Thank you in advance...
