在每一个字符串的结尾，很可能得到只有一个或者两个单词的chunk，例如，下面的chunks拥有相等的长度且单词长度的方差也相等。

At the end of each string, it is very likely to have chunks with only one or two words.

产生的原因在于单位权方差与分布的总体方差不相等。

The cause is that the unit weight estimation variance and the generality variance of the distribution don't equal with each other.

There's no correlation between them ... and that means that the variance-- and I want to talk about equally-weighted portfolio.

它们之间没有相关性,也就是说。。。方差-,我想讲一下,权重相等的投资组合。

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。
