I have been used it for quite some time. Here are my 2 cents.
This camera is a modification of Polaroid Land Camera.
1. It is a specialty camera, not your do-it-all LF camera.
If you intend to put it on your tripod, I would say forget about it, go get
a 45N2. IMO, Saber is best suited to shoot enviromental portraits. It is
never intended to be used to shoot architecture or serious landscape. I
think there are quite a few rangefinder experts here, so I will stop here. I
would say 85% /15%, 85% ha... 阅读全帖

bob litterman那本书主要是 black litterman model,除了我们,基本没什么人用的。

I remember Emanuel Derman and Bob Litterman both worked at the firmwide Risk
Department of GS, Bob was the head of the group, Derman wrote extensively
on risk.

Show
haha, good.
This is huge SOB sb in all senses.
I preferred Leno to him in night talk show.
If only this "litterman" knew that he should not have made the joke about
Sarah Palin's daughter months ago.
of course he "apologized" - then he learned a lesson?
Now he'll be the joke BUTT of all American hypo-nippo dicko mofo.

标 题: Career Path 的迷途中~~
发信站: BBS 未名空间站 (Tue Dec 29 20:39:59 2009, 美东)
各位大虾帮忙指点一下,现在很迷茫ing...
我刚毕业,暑假实习纽约一小公司做的Quant Developer,Play with Black-litterman
and C++.. 编程背景很弱,都是这一年的多突击学习的,没有什么实际的prgramming
project经验。暑假实习到后面做的很痛苦,看到程序就本能的反感。
我原来是学自然科学的,跟Quant相差甚远,所有的一切都是这一年半积累的,学的很
辛苦但是很充实,我确认这些是自己感兴趣的但是又不确定怎样选择自己的career
path. 面过几个quantitative analyst 职位最终都被据了,受挫的同时在怀疑自己到
底适不适合做Quant. 我,girl,喜欢challenging的东东,喜欢绞尽脑汁的工作,活泼开
朗,喜欢一半跟人打交道一半有技术含量的工作,不想做

来自主题: Quant版 - 什么是bayesian optimization?
靠,这个得要我命
我是实用派非搞学术的,只要个general idea 稍微编点程序都行,optimziation得给我
明确的objective,subjective function. black litterman照着paper也能编一下,再复
杂的像这种的就算了,一眼望去全是数学公式到最后说什么也不知道有意思么
其实我的问题很简单,比如我现在有10个股票的数据,bayesian optimization,或者
beyesian whatever到底想干嘛? 能干嘛?

来自主题: Quant版 - 什么是bayesian optimization?
很奇妙
这样的话需要增加一个主观的prior input
运用在optimization中只不过是将mu,stdev换成conditional的了.和black litterman
基本上是一回事...
太搞了

I heard that they use Black-Litterman model a lot for asset allocation. And
in general, I believe statistics is an important part when it comes to
portfolio allocation and risk/return analysis. Would be curious to know what
they quiz you on :)

最后一段 "Second-Order Cone Programming" 是告诉观众们 他们的 portfolio

the TC term 应该是 有理数次方 (e.g. trades.^2 or trades.^(3/2) )。 只有
有一句话“techniques of Bayesian return forecasting” 偶没有完全看懂,不知道
是说在return forecasts过程中用了 Black-Litterman shrinkage,还是说用了dummy

Sure, portfolio optimization (especially TC-aware type) is a very useful
subject for practioners and the pm industry. The thing is, what is tricky
and important in practice (hence I think worth academics' decent attention)
is that even if the jointly Gaussian assumption holds, we should keep in
mind that the Expected Return vector and the Covariance Matrix are always
estimated as opposed to knowing their oracle value, hence robustness
concerns and the corresponding techniques (Black-Litterman sh... 阅读全帖
