Homework Answers
Answer: (C) survival time. ( Kaplan-Meier method is a useful method that may play a significant role in generating evidence-based information on survival time, it is often used to measure the fraction of patients living for a certain amount of time after treatment.)

Cutler (2007) uses cost-effectiveness analysis to measure the value of revascularization (bypass surgery or angioplasty) after a heart attack. According to his estimates, the cost effectiveness for this medical technology is $33,246 per life-year saved. Is this procedure cost effective? Why or why not? Would your answer change if the cost per life-year saved was double that amount?

This is a statistic question from survival analysis data Question: The Gompertz distribution is commonly used by biologists who believe that an exponential hazard rate should occur in nature. Suppose that the time to death in months for a mouse exposed to a high dose of radiation follows a Gompertz distribution with 0.01 and 0.25. Find (a) the probability that a randomly chosen mouse will live at least one year, (b) the probability that a randomly chosen mouse will die...
