• 峰度

  Coefficients of skewness and kurtosis, belonging to complex cepstrum coefficient of pure and stego speech, are compared and trained for thresholds,which used for blind steganalysis of echo hiding.

  通过对原始语音样本和藏密语音样本复倒谱偏度和峰度的学习和训练,分别得到偏度和峰度阈值,并将其用于回声隐藏的盲检测。

• 峭度

  The skewness and kurtosis have close relation with aging process, which skewness decrease and kurtosis increase with the aging time.

  局部放电统计参数偏斜度和峭度与老化程度有密切的关系，老化程度越严重，偏斜度越小，峭度越大。

计算机科学技术

• 峭度

  Moreover, the algorithm can work well in some adverse situations when the kurtosis values of some source signals are very close to each other.

  特别是，当有多个源信号的峭度值接近时，也能提取出清晰的源信号，并将其成功应用到直接提取胎儿心电图中，取得了不错的效果。

经济学

• 峰度

  In end, we build the model including the risk factor: Unconditional beta, relative condition beta, skewness, kurtosis.

  因此最终我们建立的模型中采用的风险因子包括:无条件贝塔、相对条件贝塔、偏度和峰度。

• 尖峰

  In the light of the high kurtosis, fat tail and lever effect of actual financial returns, the EGARCH-GED model was employed in order to estimate the risk of a portfolio.

  针对实际金融数据的尖峰厚尾性与杠杆效应,风险度量采用EGARCH-GED模型。
