仿真结果距离检验方法和TIC方法对比分析
Comparison between distance test method and TIC method for simulation results

摘要: 针对仿真结果动态一致性的检验,将距离检验方法和TIC(Theil's inequality coefficient)方法进行了对比分析.距离检验方法可以在一定显著性水平下给出一致性检验的拒绝域,在时域内实现了定量检验.TIC方法的检验指标是TIC系数,经过研究发现,TIC系数的计算结果可以通过坐标原点的选取而进行人为调整,大大增加了误判的可能性,所以TIC方法既不能定量检验,也不能有效的定性检验.对比研究表明:距离检验方法不受量纲、坐标原点选取等因素影响,其检验结果具有更高的可信性.

Abstract: According to dynamic consistency test of simulation results,comparative analysis of distance test method and TIC(Theil's inequality coefficient) method was given.As the rejection regions for dynamic simulation result test were obtained at a given level of significance by the distance test method,quantitative test of dynamic consistency was realized.TIC coefficient was used to test the simulation result consistency,but the coefficient could be affected by selection of coordinate origin,causing possibly misjudgement.Therefore,the method cannot realize quantitative test,nor realize effectively qualitative test.The comparative analysis shows that the distance test method will not be affected by dimension and selection of coordinate origin,and reach a high credibility of test results. -
