小弟正在上图形学的课,但老师给出的fianl project 确实做不来,只做了一部分。
如果哪位大牛对图形学感兴趣,请给我一点提示,谢谢。这学期过不过就靠这个fianl
project 了。
留学学习辛苦啊,大家体谅体谅!

Hi,
Continue on the project, I would like to post the preliminary result of
backtest for all SP500 underlyers using Moving Average Stategy for the last
10 years: (ie, buy/sell signal by crossing of 10day and 25day average ).

下界正确。上界不对。(a+b)没有上界。
如果你学过线性模型理论,从几何的角度看y, x1, x2 这三个向量,你会发现只要他们
的相对位置合适,可以使得 a, b 很小,而(a+b)很大。
用下面的假数据:
y x1 x2
0.5 0.001 0.0015
1 -1 -0.9991
0.5 -0.001 0
1 0.89 0.94
SAS run 出来的结果是
R^2(x1)=0.0017, R^2(x2)=0.0005
R^2(x1,x2)= 0.9998

来自主题: Statistics版 - R square接近零是怎么回事
请教一下,我不太懂这个:有个dataset大约3万record,做了一个multivariate
regression,其中dependent var是「hours needed」,是continuous的,三个
independent var,其中两个是值为0/1的categorical var「daytime_or_not,
weekend_
or_not」,第三个是个continous。简单用excel的regression tool run了一下,怎么r
square只有0.0015,是不是这方法根本就用错了?

呵呵,你真花时间去研究了。不过你用的是 5 张牌的情况,不适用于 Texas Hold 'em
. 另外在你所说的情况下,Royal Flash 概率应该是 0.0015% / 10 = 0.00015%, 4
Aces 概率因该是 0.024% / 13 = 0.0018%.
在 Texas Hold 'em 出现 Royal Flush vs 4 Aces 的概率应该小于
( 4 x 44 ) / C (52, 9)
C(52,9) 是 52 张牌里选9张的组合的可能性,也就是 52! / ( (52-9)! * 9! ) = 3.
68E+9.
那么 Royal Flush vs 4 Aces 的概率应该小于 4.78 E-8. 有兴趣的同学,可以去算一
下确切的概率。 呵呵。
