二、具体算法展示 rate = events /person-years *1000 upper limit = (1000/person-years)(events+(1.96*sqrt(events))) lower limit = (1000/person-years)(events-(1.96*sqrt(events))) 欢迎和大家一起交流成长。
What is a confidence interval? A confidence interval is a range of estimates in a sample distribution where a true population value lies, with a certain level of confidence or probability. Confidence intervals are often used to determine the certainty of a true estimated value (such as a mean...
