: What is the hazard ratio between Person 1, a 40 year old non-smoker, and Person 2, a 30 year old smoker? View
: Now assume that the hazards for patient 1, h_1and for patient 2, h_2 are proportional to each other. Also assume that S_1(T) > S_2(T) for some T > 0. Then which of the following is true about the hazards? View
: Person 1 has hazard h_1(t) = 1, and Person 2 has hazard h_2(t) = 2. What is the probability of dying within the first year for each patient? View
: Using the Nelson-Aalen estimator estimate H(7), the value of the cumulative hazard at t=7 for this dataset. View
