Gaussian distribution（高斯分布），又称正态分布（Normal distribution），是统计学和概率论中最重要的连续概率分布之一。其名称来源于数学家卡尔·弗里德里希·高斯，但历史上其他学者（如亚伯拉罕·棣莫弗和皮埃尔-西蒙·拉普拉斯）也对其发展有重要贡献。
基本形式
高斯分布的概率密度函数（PDF）为：
$$
f(x) = frac{1}{sigma sqrt{2pi}} , e^{ -frac{(x - mu)}{2sigma} }
$$
其中：
钟形曲线
图形呈对称的钟形，峰值位于均值 $mu$ 处，两侧逐渐衰减。约68%的数据落在 $[mu-sigma, mu+sigma]$，95%在 $[mu-2sigma, mu+2sigma]$，99.7%在 $[mu-3sigma, mu+3sigma]$（称为68-95-99.7法则）。
高斯分布因其数学性质（如可微性、闭包性）和实际适用性，成为科学和工程领域最广泛使用的概率模型之一。
