I am replicating a lifetime risk analysis that the CDC put out a few years ago regarding HIV infection among race and risk category. Currently the process uses a program called DEVCAN which was built for calculating lifetime cancer mortality. PROC LIFETEST is the only SAS procedure that is close to what I need.
Its looks as though PROC LIFETEST, for survival analysis starts with a cohort and follows that group over time. Well, I am conducting this for an entire state's population and don't have each citizen as an observation. Is there a way to calculate with LIFETEST using this data format:
AGE POPULATION RACE SEX RISK HIV_POS
1 8,000 White F None 5
2 9,000 White F None 0
3 10,000 White F None 0
85+ 13,000 White F None 7
1 8,000 Black M None 8
...Instead of having each line be an observation like i have seen in each paper and example so far?
