Let’s say the mean of precision and recall is at least 0.75. Which of the following could be the true value of the…Let f(x) be the probability that a person with feature x dies within 5 years. Let Sx(t) be the survival function of a person with feature x. Assume t is measured in years. Which of the following is…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?What is the hazard ratio between Person 1, a 40 year old non-smoker, and Person 2, a 30 year old smoker?You have a model such that the lowest score for a positive example is higher than the maximum score for a negative example. What is its ROC AUC?When we’re using a normal approximation, the width of our confidence interval depends on the variance of the normal distribution.
