Which risk assignments would make this pair concordant? Compute the Harrell C-index for the following dataset and risk scores: 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? 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? What is the hazard ratio between Person 1, a 40 year old non-smoker, and Person 2, a 30 year old smoker? Which of the following interpretations is most correct? Which of the following is true about the hazard of patient 1 and 2 at time T? Assume h_1(t) = t, and h_2(t) = 1.0. At which time T > 0 does S_1(T) = S_2(T)?
