[R] PH Model assumption

[Ashta]

Hi all,

I was trying to test the assumption of proportional hazards
assumption, I used the cox.zph function

>cox.zph(coxfit6)

Results are:
               rho        chisq        p
x1          -0.0396    1.397   2.37e-01
x2           0.1107    9.715   1.83e-03
x3          -0.0885    7.743    5.39e-03
x4           0.0366    1.092    2.96e-01
x5           0.0242     0.455    5.00e-01
GLOBAL     NA     30.952    9.57e-06


Are all these covariates fulfilled the assumption of proportional hazards?

Thanks again.
