问题如下：
How does Gaussian white noise differ from general white noise?
选项：
解释：
General white noise can have any distribution and does not have the be independent across time. Gaussian white noise is iid, and each shock is normally distributed .
普通白噪声应该是服从正太分布的吧，我看在线性回归中关于error term的assumption中最后一条说The error term is normally distributed.（讲义170页）.普通白噪声性质可参考回归中error term的assumption吗？
