经济学家 Hal R. Varian,有个小散文叫:How to Build an Economic Model in Your
Spare Time(via: Kzeng),[link: http://www.ischool.berkeley.edu/~hal/Papers/how.pdf]对别的学科的人也会有启发吧。摘录几段:
The first step is to get an idea. This is not all that hard to do. The
tricky part is to get a good idea. The way you do this is to come up with
lots and lots of ideas and throw out all the ones that aren’t good.
But where to get ideas, that’s the question. Most graduate students are
convinced that |

t**********6 发帖数: 565 | 7 前段时间在弯曲(San Francisco) 附近找工作,自己也整理了一些找机械背景的公司。
现在尘埃落定,跟大家分享一下,希望起到帮助。题目起的,是吸引眼球,我承认。。。
斑竹,也看着给个包子:)
也欢迎大家添砖加瓦,完善这个列表。
弯曲总体上自然是马公的天下,但是仔细找找,机械工作的机会并不比别的区域少。当
然,传统的机械公司不多,主要集中在消费电子业,半导体,医疗器械,新能源等领域
。下面这个表是我自己整理的,如有疏忽之处,大家也多提意见。

最近要买一台GC/MS,哪家的售后服务好?软件操作比较简单?仪器比较稳定可靠?
目前主要在Agilent, Varian, and Shimadzu中选。
有用户经验的给说说,多谢! |

Several large outsourcing firms made important tuck-in acquisitions, many
mid-sized firms expanded their platforms with strategic acquisitions, and
one outsourcing firm successfully tapped the equity market for an Initial
Public offering (IPO). But the big stories in the pharmaceutical outsourcing
industry in 2009 involved seven “going private” transactions and fifteen
separate divestitures. During the past few years, both in these annual

大牛虐待学生和同行相轻才是主流和普世真理--这常常被主流的温情主义所掩盖。
激光的发明人,很多人很不熟悉的MAIMAN就是被大牛们迫害。
MAIMAN 在STANFORD博士论文期间,为LAMB 的NB奖工作做了一
套非常规的真空装置,得到了初步的数据,但是LAMB 更喜欢能吹牛的MAIMA
N的师弟,WIEDER。 LAMB 还有意让MAIMAN晚毕业的半年来伺候WIE
DER 用这套实验装置做实验拿数据,理由是MAIMAN的法语不过关。而后来W
IDER的论文里面连MAIMAN的一个字也没提。
MAIMAN是如何发明世界第一个激光的
MAIMAN的毕业论文为LAMB获得诺贝尔奖立下了汗马功劳,结果却被LAMB赏识的另一个会
吹牛的学生(WILDE)搞去吹牛并且去了当时的西屋而他却不能。WILDE后来在西屋和
SCHALOW合作搞出了一个他们后悔一辈子的错误结论:红宝石是不能做激光的,并且在
第一届国际量子电子学会上宣读。MAIMAN也是在这个会议上听到了这个他嫉恨的师弟和
傲慢的schalow的结论,他长期做红宝石MASER的经验告诉他复仇的机会来了。... 阅读全帖 |

T*******I 发帖数: 5138 | 36 请问,以下对Bootstrapping法的描述是正确的吗?
In statistics, bootstrapping is a computer-based method for assigning
measures of accuracy to sample estimates (Efron and Tibshirani 1994). This
technique allows estimation of the sample distribution of almost any
statistic using only very simple methods (Varian 2005).[1] Generally, it
falls in the broader class of resampling methods.
Bootstrapping is the practice of estimating properties of an estimator (such
as its variance) by measuring those properties when samp... 阅读全帖 |

years will be statistician ... The ability to take data – to be able to
understand it, to process it, to extract value from it, to visualize it, to
communicate it – that’s going to be a hugely important skill in the next
decades.”?
Hastie: Isn’t that great? When I was at school, we were the nerds. Now we
are sexy! Wish I could be back at school.
Hastie老师您就别想返老还童了,学您死党Tibshirani多收几个美女PhD是正道... Lol

Google. "The smartest person in the world could well be behind a plow in
China or India. Providing universal access to information will allow such
people to realize their full potential, providing benefits to the entire
world."
