And then we try and get our simulation to match the past, and hope that that will help it predict the future.
尝试让仿真程序能和这一部分实际数据相符,并且希望它能够帮我们对未来进行预测。
So in fact, it is the case, if you look at data, and by the way, that's the way I ended up setting a lot of these parameters and playing with it, was comparing what my simulation said to historical stock data.
所以实际上,在这个例子中,如果你看到数据,顺便说一下,这就是我设置很多变量,然后编程的方式,也就是把我的仿真程序得到的结果,和历史股票数据进行比较。
