There's also another variance measure, which we use in the sample-- There's also another variance measure, which is for the sample.

还有另一个离散指标,我们用以考察样本,这是另一个离散指标,用于考察样本

So in return to, we have a slight variance here, -- where I'm defining apparently -- declaring a function called cube.

作为应答，这里我们有一点变化，这里我显然定义了-,声明了一个叫做cube的函数。

I feel like I have to introduce concepts like variance and co-variance and correlation in order to talk about finance; so that's what we'll do in Lecture Two.

我会讲到像方差,协方差,相关系数,这样的概念,为金融学的内容作一些铺垫,我们会在第二课讲到

Now, underlying our theory is the idea that we measure the outcome of your investment in your portfolio by the mean of the return on the portfolio and the variance of the return on the portfolio.

而理论的基础是,我们通过计算,组合收益率的均值，和组合收益率的方差,来衡量一个投资组合的优劣。

x1 The portfolio mean and variance will depend on x1 x1=1 in the way that if you put--if you made x1 = 1, it would be asset 1 x1=0 and if you made x1 = 0, then it would be the same as asset 2 returns.

投资组合的均值和方差取决于1,如果你令，投资组合的均值方差就与第一项资产相等1,如果你令，那么它们就会与第二项资产的参数相等。

And in this context, the length of that array is stored in Arg C. Well, let's take a look at a slight variance of this that reveals further what we can do and reveals what a string really is.

关于这点，那个数组的长度被存储在ArgC中,好的，让我们看看这个轻微的变化,那个揭示了我们可以做的,和字符串实际上是什么。

They divide by n-1 to make it an unbiased estimator of the population variance, but I'm just going to show it in a simple way here.

当除以n-1表示的是对总体的,无偏估计,我在这里只是说的简单一点
