Kurtosis is an effective characteristic value for assessing the number of peaks in a signal. Kurtosis (peakedness, fourth statistical moment) is defined as the ratio of two statistical characteristic values/processes.
Kurtosis is a type of weighted Crest factor. The signal peaks are valued higher than the "signal noise" (also called the carpet value) due to the fourth power of the integral. Not only is the RMS value also used, but the entire signal progression as well. This increases the informational value of this characteristic value.
峰态系数（峭度）是用于评估信号中峰值数量的有效特征值。峰态系数（peakness“峰度而不是峰值”，四阶标准矩/M4）被定义为两个统计特征值/过程的比率。用来描述数据扁平程度的。
峰态系数是 Crest factor 的一种加权值。 由于积分的四次方，信号峰值的值高于“信号噪声（signal noise）”（也称为地毯值）。不仅使用了有效值，还使用了完整的信号序列，这使得该特征值需要更多的信息量/维度。
Information: 说明:
The kurtosis factor is standardized at 0 in the module. A kurtosis factor of less than 2 is typical of a machine in good condition. 峰态系数在模块中被标准化为0。 峰态系数的值小于 2 是处于良好状态的机器的典型值。 |
