Where
Res[f(x),n] is the sum of residues on the real axis
and
Res[f(x),m] is the sum of residues on the upper plane
In your case, there are two simple poles on the real axis. Just add residues

x=2 if red

then sum up all x_i (i=1..N) and divide the sum by 3, get the residual, say
r_n. the last people always tells others the color according to this
residual, i.e., r_n=0-->white, r_n=1-->black, r_n=2-->red.
based on r_n and the residual r_{n-1} calculated by the N-1th man, the N-1th

发帖数: 965 | 23 这个我不清楚。目前公司的做法是获取多个单晶结构，然后评估到底蛋白质有多大的
flexibility。
就拿酶来说，一般来说基本的hinge结构比较固定，但是其他residue比较flexible （
比如说activation loop）。也许结构生物学不能告诉我们如何才能抓住这些residue（
一般来说这个是最重要的问题。由于同一个family绝大多数的酶hinge部分比较相似，
所以只有抓住这些较为特异的residue才能改善活性和选择性），但是的确能指导大概
什么样的presentation of functionality可以有起码的ligand－target作用。从这个

improvement on the residual justify the necessity of invoking the

regression model observed in the equilibrium market. That is, the mean of

initially we won't assume the mean of residual is vanishing, but later on,
the arbitrage free assumption guarantees that the the mean of residuals is
zero. |

发帖数: 744 | 30 Apply the power series of sin to A.
Here is my 2cents.
Note that sin(x)^2 + cos(x)^2 = 1 is an identity as formal power series.
When you restrict to the n-th order polynomial, it gives
[sin(x)^2 + cos(x)^2](n) = 1
up to a residual of higher order terms.
In the case of sin(A) and cos(A), the residual about the n-th order tailor
polynomial consists of summands like A^i/i!, which makes the residual go to
0 as n goes to infty. So after taking the limit
sin(A)^2 + cos(A)^2 = 1. |

y = 10*sqrt(t) + rnorm(9501,mean=0,sd=10)
x和y的correlation ~ 0.98(他们各自不stationary)， 但是他们的trend本质上不同的。
有另一个idea：对每个组，取一个做为y，其他都是x, 如x1, x2,...,xm.
直接regress y on (x1, x2,...,xm)，包含intercept。虽然xi都不stationary但是

使得residual=y - beta*X的variance尽可能的小，所以这样得出的residual是最有可

(1) fitting 之后 产生residue和x-square，你可以把每个residue乘以你每个dy，这
样如果dy不一样，最后weighted residue、x-squre也不一样.或者用weighted fitting，这样x-squre 就会有区别。 但是仍然不能把dy 计到

(2) 如19楼你自己理解的，一开始不能平均，而且要更多的实验重复，比方说100次（
那你要疯了）。然后每一组go through all steps.最后看dA dB的分布，这是标准做法
（3）不要叫真。拟和要求error为高斯分布，你对数据已经进行了n步处理，你的ln(K)
和ln(K/M)的error根本不知道已经变成了什么分布了，按理来说你根本不能做普通的x

I have a vector X and want to calculate the sum of squared residuals (SSR)
at each data point.
SSR at data point m consists of two parts. The first part is the sum of
squared residuals for all data points before m, and the second part is the
sum of squared residuals for all data points after m (see below formula).
SSR(m) = sum_i (X_i - X1_bar)^2 + sum_j (X_j - X2_bar)^2, where i is from 0
to m and j is from m+1 to n. X1_bar and X2_bar are the means for each

because response = mean structure + error
since error is usually assumed to normal

数据不normal的话，一般transform or use generalized models

如果我这么要价，算高还是低？
36 months, 10k miles/yr, residue 60%
0 down
我要价monthly payment = MSRP *40% / 36, before tax
这个倒是很直观，就是不知道是要高了还是低了
比如,
我看了一款228i, MSRP $45k, dealer给的: residue 63%, money factor 0.0017,
monthly payment $586 before tax ($638 after tax)
按我以上要求，我会要价$500 before tax
这样我出价太低吗，还是有可能拿下？
如果我email dealerships with my formula, 要price quote，会被羞辱么还是会有
dealer考虑？
我在湾区，貌似这边车贵。有没有推荐的bmw dealer? |

其实bmw这个lease,核心就是两个,一个是money factor一个是residual value %
lease计费,说白了就是你付lease期间的折旧,加上对应的资金成本
折旧=成交价-到期残值,到期残值=MSRP*residual value %
资金成本就是每个月交(成交价+到期残值)*money factor
这里的money factor你可以类比成apr,但是因为上面的计算公式,实际上是apr/24
(相当于apr/12是每月利息比例,作用在成交价和到期残值的平均值上
那么每个月交的利息就是(成交价+到期残值)/2/(apr/12),
后面一项apr/24就是money factor
那么具体你谈一个deal,money factor和residual value都是bmw定好的
比如x5现在三年36k残值设定是60%,money factor默认是0.0013
那么你要和dealer砍的就是成交价.
另外bmw是你可以付押金来减money factor,我理解就是相当于付了押金,
降低了default风险,因此利率也会降.每付一个lease mo... 阅读全帖 |

那才叫给力。普通三系68%的residual也不是没有出现过。 |
