Replace magic-g in g-formula implementations
Both TimeFixedGFormula
and TimeVaryGFormula
leverage a "magic-g" factor to implement custom treatment plans (i.e. treatments aside from "all" and "none" specifications)
As discussed in #61 it is not readily clear to users that the magic-g factor exists and is necessary. While in the function documentation and on the website, it would be beneficial to be clearer. For now, I am going to attempt to make the documentation clearer. If I find an adequate solution (that works for both implementations), then I will make that transition in the future.
Bandage for Current
-
[ ] Make better documentation available on both website and function documentation
-
[ ] Create a better warning/error handler for when the magic-g is NOT specified
Requirements
-
Evaluate the data row-by-row
-
Needs to be able to handle multiple conditionals
Alternatives
-
pd.query()
looks promising. However, it does not evaluate as I would hope. It returns thedf[...]
data. What I would like it a vector of0
and1
(or others depending on variable type). -
pd.eval()
look it to
The magic-g will not be used by IterativeCondGFormula
from v0.6.0 onwards. Rather the iterative conditional g-formula takes a list of treatment values. You can also generate a matrix of the treatment plan and pass that to this g-formula.
None of the other g-formula implementations have this type of behavior. I needed to use this since custom treatments are hard to specify otherwise in this g-formula
