A new periodogram was proposed using one-way analysis of variance (ANOVA), termed ANOVA periodogram, in order to reveal a precise significant periodicity. Thirty 3-day complex computer-simulated time series with known periodicity (24 h) and three 2-h data-missing occurring periodically (23 h, 20 min) were used to compare the ANOVA periodogram with Enright's one. In results, the ANOVA periodogram was superior to Enright's periodogram in the accuracy of assessing the major periodicity.
为了揭示精确的显著周期性,提出了一种使用单向方差分析(ANOVA)的新周期图,称为方差分析周期图。使用30个具有已知周期性(24小时)的3天复杂计算机模拟时间序列和3个周期性出现(23小时20分钟)的2小时数据缺失情况,将方差分析周期图与恩赖特的周期图进行比较。结果表明,在评估主要周期性的准确性方面,方差分析周期图优于恩赖特的周期图。
