Hi Everyone,
Above is my survival data set. and I want to have hazard rate and 95%CI for each level of 'group'.Can I use proc lifetest or proc phreg to have my results?
Thanks so much for your help,
Xinjian
I have tried below sybtaxes (status: 1=stroke, 0=no stroke)
proc lifetest data = want plot= survival (nocensor failure );
time time*status(0);
strata group ;
run;
proc phreg data=want;
class group (ref='1');
model time*status(0)= group/ rl ;
run;
I just cannot get Hazard rate (I don't get hazard ratio) and 95% CI for four levels of group. The output shoulb like this table below.
group |
N |
stroke |
Hazard rate |
95%CI |
1 |

2 |

3 |

4 |
Is it possible SAS 9.4 can give results like above?
THanks,
XD
