峰度(Kurtosis)和偏度(Skewness) 如上图所示,可以看到与使用matplotlib作的直方图最大的区别在于有一条密度曲线(KDE),可以通过设置参数去掉这条默认的曲线。另外,由上图可以知道房价呈现正态分布,还可以看到两个统计学中的概念:峰度(Kurtosis)和偏度(Skewness)。 峰度:峰度(Kurtosis)是描述某变量所有取值分布形态陡缓...

偏度(skewness)和峰度(kurtosis) 偏度偏度(skewness),是统计数据分布偏斜方向和程度的度量,是统计数据分布非对称程度的数字特征。定义上偏度是样本的三阶标准化矩。偏度定义中包括正态分布(偏度=0),右偏分布(也叫正偏分布,其偏度>0),左偏分布(也叫负偏分布,其偏度<0)。 峰度 峰度(peakedness;kurtosis)又称峰态...
