摘要
讨论了滑动平均情形下的相关显著水平估计,结果发现,在相同的自由度下,序列经过滑动平均后的相关系数临界值大于未经过滑动平均时的相关系数临界值,而且相关系数临界值随着滑动平均阶数的增加而增加.
The correlation coefficient variation before and after moving average is discussed. The correlation coefficients would increase under the same degree of freedom after moving average and the threshold values of correlation coefficients are increasing along with the increase of moving average degree.
