In this paper, a new nonparametric method for testing the difference between two groups of time series is considered. A difference index between the two groups, based on the mathematical notion of norm, is introduced. Then, the statistical significance of the observed difference is assessed by means of a randomization procedure. The percentages of alpha and beta errors are evaluated by means of computer simulation. The method is also applied to a set of experimental data and the results are compared with those obtained by means of Student's t-test.
本文考虑了一种用于检验两组时间序列差异的新的非参数方法。基于范数的数学概念引入了两组之间的差异指数。然后，通过随机化程序评估观察到的差异的统计显著性。通过计算机模拟评估α错误和β错误的百分比。该方法还应用于一组实验数据，并将结果与通过学生t检验获得的结果进行比较。
