Hi StataList,

I'm trying to use the stset command for survival analysis:

Code:
stset failure1_day_iop_criteria_op1_2x, failure(failed1_iop_criteria_op1_2x==1) scale(1)
.

However, I am getting the following error:

Code:
variable _d already defined
r(110);
I've not been able to figure it out in looking at the r(110) error code.

Any advice would be really appreciated. Thanks, William.

Code:
