摘要
采用两组不同监测数据建立非等时距GM(1,1)模型,引入平均相对误差与灰色关联度两个指标,为精度检验分级提供更多参考依据。
The unequal time - interval GM （ 1, 1 ） model established by two groups of different monitoring data is adopted, and two indexes of average relative error and grey correlation degree are introduced, providing more reference basis for accuracy test classification.
