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...

In this post, we’ve discussed the concepts of kurtosis and skewness extensively. We started with a foundational understanding of a normal distribution – the standard way data can be spread out. Subsequently, we understand kurtosis, learning how it shows whether data has heavy or light tails an...

Kurtosis and Skewness are very close relatives of the “data normalized statistical moment” family – Kurtosis being the fourth and Skewness the third moment, and yet they are often used to detect very different phenomena in data. At the same time, it i
