戴蒙德等人提出了测定诊断试验受检者对选择偏因的敏感度及特异性的一种独特方法。他们的方法包括两个步骤:首先,第一步是根据全部可得资料核算疾病的预测概率;其次,第二步是用这种作为回归模式自变量的预测概率和作为因变量的可以观察的、实在的试验部分在一起计
Diamond et al. proposed a unique method for determining the sensitivity and specificity of subjects in diagnostic tests for selection bias. Their method consists of two steps: First, the first step is to calculate the predicted probability of the disease based on all the available data; secondly, the second step is to use this as the predictive probability of the regression model independent variable and observable as the dependent variable. The actual test part together
