I'm a Survivor
With this type of exposure, each person can only have up to 2 rows
Non-reversible dichotomies
In this type of analysis, every person has a row for each person period
Discrete survival-time analysis
This is a requirement in all survival analysis (hint: not about exposure)
Binary, non-recurrent outcome
In this survival there is usually one row per person, if the variables are all measured at baseline
Continuous survival time
How do we handle time-varying exposures in discrete vs. continuous?
Continuous - new row required each time a covariate changes
Discrete- summarize exposure for each person-period, don't need to change structure of data
