摘要 本文建立了行列资料诊断试验预告值和准确度的一次性标化方法,省去了标化过程理论样本Nt的设定和求有关理论值的计算过程,导出行列资料中标准化Ⅰ级阳性预告值和标准化Ⅱ级阳性预告值、标准化Ⅰ级阴性预告值和标准化Ⅱ级阴性预告值、标准化可疑预告值和标准化准确度的一次性标化公式。分析了标化与非标化预告值的关系及转化规律。 The standardized formulae by one step for the first grade of Positive predictive value ,second grade of positive predictive value,first grade of negative predictive value,second grade of negative predictive value,suspicious predictive value and accuracy have been deduced. The relationship and regular of the standardized with non standardized predictive value were analysed.
