标 题: 可以用MGF(moment generating function)方法求取非连续变量吗？
发信站: BBS 未名空间站 (Sat Feb 2 01:09:50 2008)
可以用MGF(moment generating function)方法求取非连续变量吗？
MGF思想是，如果{X1, X2,...XN} is a sequence of independent (and not
necessarily identically distributed) random variables, 那么其和M(X)=X1+X2+..
+XN的概率密度函数可以表示为M(X)=M(X1)*M(X2)*...*M(XN)，从而可以通过Xi的密度
函数f(xi)反求其和M(X)的密度函数表达式。
但能够用以上方法求解非连续(non-continuous)的密度函数分布吗？就是说如果Xi是非
连续的离散变量，也可以用此MGF思想吗？

最近实在太忙了, 几乎一点时间都抽不出来更新这里,甚至是连听音乐的时间都没有.昨天
晚上终于有了一些空闲来听听音乐,便随手拿出这张闲置很久的Peter
White的专辑来听, 当熟悉的旋律流入耳鼓的时候, 无意当中看到唱片
内页的一个小故事,Peter White写的一段他在夏维夷的经历. 在那里他遇到一个男孩, 那
个男孩决定在Peter White的音乐会上向她女朋友求婚, 后来一切都非常顺利的进行着,当
Peter White在台上要求这对年轻的情侣上台的时候,那个女孩子根本就不知道怎么回事,
而当那个男孩通过麦克风发出他的求婚宣言的时候,全场都为之疯狂, 而Peter White用他
的音乐灵感记录了这段令人激动的场景, "Perfect Moment"这首曲子诞生了.
虽然对于非常内敛含蓄的中国人来说, 这样的情景不会多见, 但对 |

By now the comparison between President Barack Obama and former-President

the overhyped "death" of the Republican Party in 1976 and 2008, both
Presidents had promised renewed peace and talks with our chief (which both
failed), and under both Presidents, the economy faltered.

发帖数: 17544 | 22 其实我是不同意假唱的
但是这里的问题是双重标准和目的和手段的问题
很多云云在说起自己的卑鄙手段的时候，总是以目的伟大光荣正确而辩护
说我们目的是好的，手段怎么样都可以，
tg当初也是非法组织，孙中山也用日本的钱等等。
但是到假唱问题了，就开始说手段如何了。
看看人家美国人怎么说？“serve the moment"
就是说目的是伟广正的，
手段呢，当然按照云云的逻辑，无所谓了。
我的观点就是，
无论你支持，还是反对假唱，
请保持一致，不要双重标准 |

是一曾长住中国的白哥们说的（很smart,funny的一人）
他来附近一城市，我开车到旅馆（in downtown）去接他到附近玩玩。GPS尚未流行，我
查好地图，接到人准备开路，没想到旅馆门口平时双向的路，挂了一单行的箭头，因路
不熟，在满地单行的downtown不知要绕多久才能回到查好的路。而逆行一个车身的长度
就可直接上想去的路，所以。。。 那哥们说you did it very well in Chinese way.

发信站: BBS 未名空间站 (Thu Feb 28 00:12:25 2013, 美东)
我拍娃最大的问题，就是当孩子看见相机，立刻会变成另外一副表情，很不自然。所以
我的策略是以远远长焦偷拍为主，跟LD配合。LD带这孩子玩，我远远埋伏好。LD跟娃娃
说，诶你们看那边是什么，然后指我的方向，娃一抬头我就照。这办法其实简单易行，
也不需要什么好镜头，我一开始用的是一个Quantaray 70-300 f/4-5.6,可能才$100左
右。用300长焦，景深小，大白天的1/500秒的快门都不成问题。如果经费不是很多的话
，走长焦路线容易拍出好的。拍好了，功劳要都给LD，你太会逗小孩了！有些时候我来
逗小孩，让LD拍。拍不好没关系，主要是镜头不给力，要是镜头再好点就好了。说不准
哪一天，LD就批准买个小白。我现在偷拍的利器，就是70-200， f/2.8 IS II

looking for," said Christian Thwaites, chief executive of Sentinel
Investments in Montpellier, Vt.
"Investors are saying, 'China is overblown—there's inflation coming, and
they're going to have to tighten up their economy,"' said Mr. Thwaites. He
said China is strong enough to grow through any anti-inflation steps.
"China may have surprised people, but I think the market has overreacted,"

Yep, the new Snake is returning to the role that made him iconic; 24 is
