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...

Normal distribution, also known as the Gaussian distribution, is a probability distribution that is symmetric about the mean,showing that data near the mean are more frequent in occurrence than data far from the mean. In graph form, normal distribution will appear as a bell curve. How can you...
