xiaojiya, 多谢多谢。
抱歉的是,我漏掉了一个条件,x非负的。g(x)也是一个非负函数。

xiaojiya, it's probably the best example to illustrate
the concept of "common knowledge":
http://en.wikipedia.org/wiki/Common_knowledge_%28logic%29
or see Terry Tao's extremely popular blog post:

WARNING: long and probably non-sense
(better off reading the links pointed above)

xiaojiya, i really cannot do a better job explaining this
than t.tao (or wikipedia). i think most ppl would be satisfied
to understand the induction proof, but as tao pointed out, the
paradox is that it seems the info from the outsider provides
no extra info (if there are more than one blue-eyed islander)
the way to resolve it is to realize that, what the outsider said
was only "kth-order knowledge" if there are

xiaojiya, note max(B_1,0)=(|B_1|+B_1)/2. the local time part is subtle

来自主题: Quant版 - a random variable question
note there is nothing special about 1 and min
[ as Z is simply max(x,1)-1 ], so this indicates
that a vanilla call/put is less volatile than the stock.
(basically following from xiaojiya's proof that
the min and max are positively correlated)
in BS world seems this easily follows from the fact
that delta is smaller than 1, but of course from the
proof above, the conclusion holds with no assumption
at all

@xiaojiya: Yes.
@topview: Maybe because I am not that good so that they'd decide to hire me in their third round interview. hehe. I did not prepare well, and I am still learning.
If you are good enough, you might need three or four rounds, I guess.
@lawbee. You actually should blame me. again, if I were the one they want exactly, I might have been discussing an offer now. unfortunately, I was not at the beginning. The good thing is that I am getting there.

no
xiaojiya说的是(X,Y)如果jointly normal,
那么任意linear combination of X and Y must be normal,
自然而然summation就是normal的,
这是exactly jointly normal的定义,和你说的correlation一点关系也没有。
