n.（统）尖削度，（曲线的）峰态；峭度；突出度（分布曲线中的高峰程度）

The distribution has high kurtosis, indicating heavy tails and a sharper peak than a normal distribution.
这个分布具有高峰度，表明尾部较重且尖峰比正态分布更明显。
The kurtosis of the data is 2.5, which suggests moderate peakedness compared to a normal distribution.
数据的峰度为2.5，这表明其峰态相对于正态分布来说是中等的。
A low kurtosis value implies that the distribution is flat-topped and has lighter tails than a normal distribution.
低峰度值表示分布顶部平坦，尾部比正态分布轻。
The financial returns exhibit leptokurtic kurtosis, meaning they have more extreme values than a normal distribution.
财务回报显示出偏斜峰度，意味着它们有比正态分布更多的极端值。
In statistics, kurtosis measures the degree of "tailedness" or how sharply peaked a distribution is relative to a normal curve.
在统计学中，峰度衡量的是一个分布相对于正态曲线的“尾部程度”或峰值的锐利程度。
A normal distribution has zero excess kurtosis, indicating that its tails are neither heavier nor lighter than those of a standard normal.
正态分布的超额峰度为零，这意味着它的尾部既不比标准正态分布重也不比它轻。
The histogram shows positive kurtosis, suggesting that the data has more infrequent extreme events than would be expected from a normal distribution.
直方图显示正值的峰度，表明数据中的极值事件出现得比正常分布预期的要少。
To improve model accuracy, we need to transform our data to reduce its kurtosis and make it closer to a normal distribution.
为了提高模型准确性，我们需要对数据进行转换以降低其峰度，并使其更接近正态分布。
The kurtosis test revealed that the residuals were not normally distributed, indicating potential issues with the regression model's assumptions.
峰度检验显示残差不是正态分布，这暗示了回归模型假设可能存在潜在问题。
By comparing the kurtosis of different datasets, researchers can identify which one exhibits more outliers or extreme values.
通过比较不同数据集的峰度，研究人员可以识别出哪个数据集表现出更多的异常值或极端值。
