如何在R中生成多元高斯随机数?
问题描述：
我们如何按照R中的高斯(正态)分布生成数据点?
How do we generate data points following a Gaussian (normal) distribution in R?
假设我想在2d(或更高维)空间中生成遵循高斯分布的点.如何使用R做到这一点?
Suppose I want to generate points in 2d (or higher dimensional) space that follow a Gaussian distribution. How do I do this using R?
答
一维:?rnorm .更多维度:安装和加载软件包mvtnorm并使用 rmvnorm().
One dimensional: ?rnorm. More dimensions: install and load package mvtnorm and use rmvnorm().
