Hi
I have some data and I want to calculate overall and disease specific survival. While the alive/dead are 1/0 for the survival analysis with censor=1, how should I code the list for disease specific mortaility. How should I code the ones that are dead, but not due to the disease in questions, 1 or 0? or should they be excluded?
Specific mortaility. "Should they be excluded?"
In no case! This is a competing risk model. I, unfortunately, have only JMP 10 versions, where is no such model. Therefore, I'll explain the scheme.
Censor code set 0 (you can leave 1, but It will be more understandable in this case).
In one column (CENSOR) we have the following codes:
1 -- dead due to the disease,
2 -- dead not due to the disease,
0 -- alive (censor).
In one (other) column (TIME) we have:
the time to death due to the disease (corresponds to 1 in column CENSOR) or
the death not due to the disease (corresponds to 2) or
the time of the last informing that the patient is alive (corresponds to 0).
The documentation on the Survival analysis is found at:
Help==>Books==>Reliability and Survival Methods
You will see examples of how to code your values
