Looking for a large dataset for survival analysis where at least one of the variables is time-dependent.
For example, this a sample dataset:
time status sex age year thickness ulcer
1 10 3 1 76 1972 6.76 1
2 30 3 1 56 1968 0.65 0
3 35 2 1 41 1977 1.34 0
4 99 3 0 71 1968 2.90 0
5 185 1 1 52 1965 12.08 1
Ideally, I would want the "thickness" time history progression for each element/row until event time.
I have had no luck to find such dataset thus far.
