Description
For datasets with a time to event/failure variable, I do not think there is any conditional independence test for censored data (e.g., log rank test, or cox proportional hazards regression). For example, I have a survival variable that is right-censored (at 30 days because > 30 day death is not pertinent to the problem). Would it be possible/feasible to add an independence test to Tetrad that can handle censored data?
I have thought about alternatives: transforming data (e.g., imputing censored times), but believe I will lose statistical power in such cases.
Thanks!
