术语“四重正态分布”的详细信息

英译术语:

quadric-normal distribution

汉语语境:

四重正态分布是一个在数学、物理及工程等领域都非常重要的概率分布，在统计学的许多方面有着重大的影响力。若随机变量X服从一个数学期望为μ、方差为σ^2的高斯分布，记为N(μ，σ^2)。其概率密度函数为正态分布的期望值μ决定了其位置，其标准差σ决定了分布的幅度。因其曲线呈钟形，因此人们又经常称之为钟形曲线。我们通常所说的标准正态分布是μ = 0，σ = 1的正态分布。

英语语境:

Quadric-normal distribution is very significent in areas such as mathematics, physics and engineering probability distribution and has a significant influence on many aspects of statistics. If a random variable X obeys a mathematical expectation for mu, then gaussian distribution, variance of sigma ^ 2 is to N (mu, sigma ^ 2). The probability density function of normal distribution expectations of mu determines its position, the sigma determines the distribution of amplitude. Because of its bell-shaped curve, people often call it a bell curve again. We say normally mu = 0 is the standard normal distribution, normal distribution of sigma = 1.
