发帖数: 101 | 13 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？

发帖数: 911 | 16 From page 11, (2.21), you can derive out the general distribution of
end-to-end distance, phi(|R|, N). All the higher moments can be derived from
here by integration over |R|^i * phi(|R|,N), d |R|. These integrations over
|R| should be simple. |

发帖数: 238 | 17 Rg is just a sum of N independent random variables, thus its distribution is
known.
Knowing this we can calculate the mean value of its moment to arbitrary order
by the characteristic function, i.e., the Fourier transform of the probability
distribution, and taking derivatives.
Check any probability book, you should find the details. |

In its zigzagging pursuit of a more nimble and effective form of
authoritarian rule, China may be having a defining moment. Its harsh
crackdown on discontented Tibetans bore the hallmarks of Beijing’s hard-
line impulses. But its decision on Tuesday to scale back the elaborate
domestic leg of the Olympic torch relay — after a flood of Internet
protests calling it insensitive — is a sign that officials are not deaf to
public sentimen |

你的作战方式跟常凯伸有得一拼。光头的作战方式是，国军如果失手，则要么keep
quiet, 要么发通告：国军已成功躲过共匪之围剿，已经逃了。如果共匪失手，则电告
全国：扫清共匪，国军之胜利指日可待。所以，光头的下场就是，蜗居一岛，喊了一辈
子反攻大陆，最后客死异乡。
还是讲讲打仗吧，书上说作战讲究天时，地利，人和。古板人熊牛不分，是牛人还是人
牛不得而知，何况有些熊人头上没长角却偏偏喜欢冒充牛人，所以我们先不谈人。所谓

predictable 这个结论真是白下了。
我还真不知道你真是一卖药的，虽然看着确实很象。我没卖过药，所以没法给人开药，
不过我对有些现象不是很理解，你是卖药的，能给解释一下吗，为什么有些秃子总喜欢
卖章光101？为什么有些卖sedative的却很容易激动？为什么卖药的自己不先服一点？
至于我从没有在版上make predictions，那是因为有自知之明，水平太烂，不想误人子
弟。所以，我对有些长得像熊，看起来像熊，走起来像熊的东西天天在那学牛样不是很
理解，当然也不感冒。
关于Buffet，看来你对他的了解跟你对股市的了解水平差不多。Buffet从不预测股市，

Each day I live
I want to be
A day to give
The best of me
I'm only one
But not alone
My finest day
Is yet unknown
I broke my heart
Fought every gain
To taste the sweet
I face the pain
I rise and fall
Yet through it all
This much remains
I want one moment in time
When I'm more than I thought I could be
When all of my dreams are a heartbeat away
And the answers are all up to me

In the melting snow on the hill-side by the sea, in the last rays of the

out across the sea; he looked toward the east, over town and shore and the
broad hills; in the background still higher peaks rose far away in the clear
sky.
The storm had lasted a long time; it had been more terrible, too, than any
