我的第9棒出发大概是周五下午6点左右。10:30am whx第一棒就出发了.我们van2直接开

想慢点也慢不下来。 可是前面的几个team拉的都比较开,追到1迈多才有我的第一个

int is represented by link list, resolve the subtraction of two such int.
struct Digital
{
short value; // {0-9}
Digital next;
}
Digital Subtraction(Digital d1, Digital d2)
The two int can be negative and the length of the two link lists may not be
the same. For example, d1 = 2->3, d1 = 1->6->5, the return value should be -

来自主题: Overseas版 - 大家帮着分析一下老板的想法吧
最近有一个课题,我大概做了一个框架,把自己的基本想法写成一份简略的三四页的文档
拿去给老板看了。按照我的设想,剩下的也就是一些实验工作了。老板先是找了一个exch
ange student来做,过了一个星期似乎对他不太满意,就把我做的另一个看起来相对容易
一点的课题交给他做,把原来那个课题的工作交给一个新到老板手下的graduate
student做。今天下午跟老板谈工作,老板把这个安排跟我说了,说那个新来的graudate
student也许会在这个课题上有什么自己的ideas,让我跟他一起完成这个课题,并且让我
advise那个新来的graduate student.
我有两点疑虑:
一、原来的设想是安排个人做做实验工作就结了,我肯定是第一作者;虽然我并不介意别
人拿出ideas来拓展这个工作,但如何确保我做为第一作者的地位不受影响?所有课题从
选题到目前为止全部由我独自完成。
二、我自己也是graduate student,老板为什么让我advise他,我又该怎么advise他呢?
这个新生和老板是同一个国家的。
这个安排会对我产生什么样的潜在影响?

Define A_n=\sum_{i=1}^n a_i, B_n=\sum_{i=1}^n b_i in which a_i and b_i are
both 无穷小量 or equivalently:
\lim_{n->\infty}a_i=\lim_{n->\infty}b_i=0
Moreover for the same i, a_i and b_i are 等价无穷小 or equivalently:
\lim_{n->\infty}a_i/b_i=1, 1<=i<=n
Now we want to prove:
\lim_{n->\infty}A_n=\lim_{n->\infty}B_n if either of the limits exists.
The above equation seems intuitively true...to me. But
it seems that the proof requires the exchange of \lim and \sum.
I am not sure the requirements for this exch

来自主题: Statistics版 - GEE model一问
诸位大虾,在下试用GENMOD with repeated option去估计一个率,看起来很简单的
model,比如这样:
proc genmod data = dsn;
class subjid y x;
model y = x/link = logit distribution = binomial;
repeated subject = subjid/type=exch;
estimate 'rate a' x 1 0;
run;
可是一旦使用了repeated option 也就是GEE model,出来的率非常邪门。如果直接
proc freq; tables y*x得到的y=1 & x=1的率是70%左右,用GEE model求出来的居然在
30%左右?我注意到用exchangeable option 出来的working correlation〉0.95,这是
不是如此离奇的rate的原因亚?那位大虾对这种情况有经验望不吝赐教,谢先

来自主题: Statistics版 - Question Proc GENMOD
I am running on the GENMOD. The data set is simple repeated measure.
The code is following.

pred = Pred

reschi = Reschi

来自主题: Statistics版 - Does GENMOD give class-level p-value?
Here is the example:
proc genmod data=data_one;
class id x1 x2 x3;
model y = x1 x2 x3 / dist=normal;
repeated subject=id / type=exch;
run;
The default output has p-values for each dummy variable generated by x1, but
not a p-value for x1.
Anyone help please? Thanks a ton. It seems GLM gives such p-values by
default.

Walmart's " rollback " price for a Blue Rhino tank exchange is $15.00 today
here in NJ. Blue Rhino has a $3.00 rebate until the end of the year. No tax
was charged, which surprised me.

post of a pretty good deal. Good luck

来自主题: _DealGroup版 - 【$】Victoria's Secret Deal
There have been plenty of posts about Victoria's Secret deals lately, but I
may have stumbled across a good deal.
Last year I ordered during November and got the Secret Rewards Card. I ended
up ordering an 2 items one that was back ordered and one that wasn't. I
received 2 secret rewards cards, one in each shipment.
Well I just bought 7 panties (7/$26) and 1 sweater ($29.50) for $55.50 plus
a Free Lip Gloss Set and Free Shipping.
The 3 codes used are:

刚才试了一下,好像没有做option的权限,IB根本不给我这个选项,股票和期货都可以
。你们有在IB能做港股Option的吗?
港股option好像品种很少的样子,都在这儿了:
