Advantage of the first serve in Badminton
In badminton, you gain a point only when you serve and win
the rally. If your opponent served and you won the rally,
you get the right to serve, but do not get a point. It seems

关于随机变量与概率论之间的一个关系
2012/08/02日记
随机变量是统计学和概率中最重要的概念。在整个数理统计学领域有一种说法是,
概率论是统计学的基础,而测度论是概率论的基础,由此,统计学被称为了一门纯粹的
数学分支学科。换句话说,这意味着一个非数学背景出生的人将没有可能性在统计学的
方法论领域做出有实质意义的贡献。他们将不会被那些数学背景的统计学家们放在眼里。
概率论以纯数学的语言对随机变量作了一种数学意义上的抽象而又严格的定义和解
释:一个随机变量是定义在其概率空间上的一个可测函数。这个概念的定义在非数学背
景的统计学家们看来是一个无法被直观理解或晦涩的陈述。
其实,我们应该知道,一个随机变量并非存在于概率论中,而是存在于现实世界里
,而现实世界是一个直观且容易被一般人类的智力所理解的存在。概率论不过是在基于
某种关于现实世界中随机变量的基本认识的基础上给出的一种理论性的解释。一旦关于
随机变量的基本认识得到深化和发展,概率论中关于它的理论性解释也就应该会被改变
。因此,当一个人谈论关于随机变量是什么... 阅读全帖

In astrophysics and cosmology, the anthropic principle is the philosophical

Again, the most simplistic model is as follows.
There are a total of t probable outcomes.
p1 is the probability for a probable risk r1 => expected e1 = p1*r1;
p2 is the probability for a probable risk r2 => expected e2 = p2*r2;
...
pt is the probability for a probable risk rt => expected et = pt*rt;
Here, ri < rj for each pair of i and j when i < j.
Normally, the best decision is to take the risk rm which has the minimal
value (em) of all the t e's.

is no such thing called real world probability, nobody has ever seen it,
and no one managed to test it by experiment. And more important real world
probability is irrelevant. Stock market and option market have their own

下几种方法:
1) 将probability score乘以一个常数,使之变为整数,再加上限,比如if score
> 100 then score=100。同时告知这个Score也可以当probability使用(除以100即可
)。但假如你的score是要卖给第三者,你就要防止别人reverse engineer你的score的
话,这个方法不能用。
2) 可以将probability score 分100等分(PROC RANK),每一等分的score为1, 2

3) 看看probability score的分布,以中值为中心,定为score=50,再向两边发散
。这样的话,你可以“制造”一个正态分布的score。
