核心释义

1. 1.

   偏斜的特性；不对称性

   The property of being skew.

2. 2.

   衡量实值随机变量概率分布不对称性的指标,定义为三阶标准矩 γ1=μ3/σ3,其中 μ3 是均值的三阶矩,σ 是标准差。

   A measure of the asymmetry of the probability distribution of a real-valued random variable; is the third standardized moment, defined as scriptstyle γ1=(μ3)/(σ3),! where μ3 is the third moment about the mean and σ is the standard deviation.
