给出了计算两项特性曲线之间精确有符号面积和无符号面积的公式。进一步证明了当c参数不相等时，两个icc之间的面积是无穷大的。讨论了准确的面积测量对项目偏差研究的意义。
Formulas for computing the exact signed and unsigned areas between two item characteristic curves (ICCs) are presented. It is further shown that when thec parameters are unequal, the area between two ICCs is infinite. The significance of the exact area measures for item bias research is discussed.
