| 摘 要： | Biomedical researchers often study binary variables that indicate whether or not a specific event,such as remission of depression symptoms,occurs during the study period. The indicator variable Y takes two values,usually coded as one if the event ( remission) is present and zero if the event is not present ( non-remission) . Let p be the probability that the event occurs ( Y= 1) ,then 1-p will be the probability that the eventdoes not occur ( Y = 0) . The odds that an event will oc-cur is a quantity defi...
