It is also the first time that the government allowed refugees to return to areas which were formerly controlled by the rebels.

Which means, next time through the loop, that's going to pop out and return an answer.
循环会跳出并返回这个答案,如果不相等的话。
I computed the average return on stocks over that time period and I computed the average return on bonds over that time period.
我计算了那个时间段的股票平均收益率,和债券平均收益率。
So this line or these lines of code up here are arguably constant time steps to say if N is less than 2 in return, that it will always take maybe one step, maybe two steps, some number of fixed CPU cycles.
如果N小于2并返回,那么这些行所对应的代码,通常只需要执行一步,或者两步,具体数字与CPU周期有关。
Over this time period, that portfolio had an expected return of something like a little over 9% and it had a standard deviation of a little over 9%.
在这个时间段,这个投资组合的预期收益率是,9%多一点%,标准差是9%多一点。
Then, once we did that we could plug that into the formula that I gave you last time and get the standard deviation of the portfolio and the expected return on the portfolio.
再将估算出的数值代入到,上节课给你们的公式中,就能得到资产投资组合的标准差,和该投资组合的预期收益率
The other thing that I mentioned last time was that there seems to be a really big difference between the expected return on the stock market and the expected return on short-term debt.
上节课提到的另一条内容是,股票市场的预期收益,与短期债券的预期收益,存在着巨大差异
