Getting Started

>>> from random_survival_forest import RandomSurvivalForest
>>> timeline = range(0, 10, 1)
>>> rsf = RandomSurvivalForest(n_estimators=20, timeline=timeline)
>>> rsf.fit(X, y)
>>> round(rsf.oob_score, 3)
0.76
>>> y_pred = rsf.predict(X_val)
>>> c_val = concordance_index(y_val["time"], y_pred, y_val["event"])
>>> round(c_val, 3)
0.72
