AUC time horizon #103

Open tommyvcc opened 1 year ago

tommyvcc commented 1 year ago

Thank you so much for the hard work I have one question regarding the AUC metric. And the time horizon. The AUC is reported as an array and the times are reported as an array.

For example, if the time intervals are 0 to 1 , 1 to 2 and 2 to 3.

And the array is ( 0,1,2,3)

While the AUC is 0.6, 0.7, 0.8

So the array is (0.6,0.7.0.8)

Does this mean that the AUC for the period 0 till 3 is 0.8? Or the AUC for the period 2 to 3 is 0.8?

auton_survival uses scikit-survival for metrics internally. Namely the metrics.cumulative_dynamic_auc: you can check in their docs https://scikit-survival.readthedocs.io/en/stable/api/generated/sksurv.metrics.cumulative_dynamic_auc.html#sksurv-metrics-cumulative-dynamic-auc
