+# About
+This dataset is a supplement to the [github repositiry](https://github.com/pfilonenko/ML_for_TwoSampleTesting) and paper addressed to solve the two-sample problem under right-censored observations using Machine Learning. 
+The problem statement can be formualted as $H_0: S_1(t) = S_2(t)$ versus $H: S_1(t) \neq S_2(t)$ where $S_1(t)$ and $S_2(t)$ are survival functions of samples $X_1$ and $X_2$.
