What is the output for a person with Creatinine = 0.8 mg/dL, Bilirubin total = 1.5 mg/dL, INR = 1.3 If a feature x has range 0 to ∞, then what is the range of ln(x)? True or False: If a > b, then ln(a) > ln(b). Which assignment of risk would make the following pair concordant? Model 1 has a c-index of 0.7 and Model 2 has a c-index of 0.6. Which is more accurate using a threshold of 0.5 for the risk score? A linear risk model for the risk of heart attack has three inputs: Age, Systolic Blood Pressure (BP), and the interaction term between Age and Systolic Blood Pressure. The coefficients for Age, BP, and the interaction term are 0.1, 0.3, and 0.5. Can you determine how an increase in blood pressure is affected by an increase in age?
