A [分析] 峰度(kurtosis)是指一个分布与正态分布在陡峭程度上的差异程度。高峰态(leptokurtic)指一个分布的峰值比正态分布更为陡峭;低峰态(platykurtosis)指一个分布的峰值比正态分布更为平缓。 如图1所示,与正态分布相比,高峰态分布会有更多的观测值集中在(算术)平均值附近(图中a区),同时会有更多远离平均值...

aFor a normal distribution, we could remove data points which are more than three standard deviations from the mean (since they have less than a 1% chance of belonging to the distribution). 为正常分配,我们可能取消是超过三标准偏差从手段的数据点 (,因为他们比属于的1%机会有发行的较少)。[transla...
