Or if you had the entire population that you're sampling from, whenever you take an instantiation of these random variables.

或者，如果您拥有要从中抽样的整个人口，则每当您对这些随机变量进行实例化时。

Or just to visualize it is that, when we take an instantiation of this very variable, we're sampling from a normal distribution, a standardized normal distribution that looks like this.

或者只是想象一下，当我们对这个变量进行实例化时， 我们从正态分布中采样， 一个标准化的正态分布， 看起来像这样。

I mean, is the best instantiation of this that countries literally divide households into different A and B categories, or something like that, so that that kind of alignment could happen?

CA：我的意思是，最好的实例是国家将家庭真正划分为不同的 A 类和 B 类， 或者类似的东西， 以便可以实现这种对齐？

So one instantiation of the random variables you sample once from the universe and you get X is equal to 1 and that Y is equal to-- let's say Y is equal to 3.

因此，你从宇宙中采样一次的随机变量的一个实例化，你得到 X 等于 1 并且 Y 等于——假设 Y 等于 3。
