Python kurtosis 計算
Web二.峰度(Kurtosis) Definition:偏度是描述某变量所有取值分布形态陡缓程度的统计量,简单来说就是数据分布顶的尖锐程度。 峰度是四阶标准矩计算出来的。 (1)Kurtosis=0 与正态分布的陡缓程度相同。 (2)Kurtosis>0 比正态分布的高峰更加陡峭——尖顶峰 WebNov 26, 2012 · By default, scipy.stats.kurtosis(): Computes excess kurtosis (i.e. subtracts 3 from the result).; Corrects for statistical biases (this affects some of the denominators). Both behaviours are configurable through optional arguments to scipy.stats.kurtosis().. Finally, the np.sqrt() call in your method is unnecessary since there's no square root in …
