USCIS officers must evaluate whether the original work constitutes major,

may be “original,” this fact alone is not sufficient to establish that the

发帖数: 166 | 2 我前面的理解可能有问题，现在我这么认为，
不一定每篇文章，也就是每一个original contribution都要有major significance，
但是至少需要有一个major significance被认定。
只有一个original contribution有major significance也不一定行，需要综合其他的
major significance，authorship和审稿一起判断(in totality)，算不算的上small
number of percentage |

发帖数: 118 | 3 如果这样的话，那么significant对于a/b/c/d是否就没有区别了。
总觉得应该是0，试想如果x4不significant，那么我们就用0；对于一个var里的各个
level而言，是不是也应该同样对待，significant就用系数，不significant就用0？ |

发帖数: 118 | 4 在fit model之前，大家并不知道X2是不是significant，也不知道x2哪些值是
significant的，等到model完成之后，大家才发现其中c不是significant。
如果X5在这个model里也是一个significant的categorical变量，且有3个值（m,n,p）m
,n的p-value均<0.05，p为baseline，这时候我们在score新数据的时候，就全部用他们
的系数（当然x5='p'时X5=0），这个没有异议吧。
这时候对比一下x2和x5，x2='c'时，该用0.3还是0？

Michigan To Audit 'Significant Mismatches' In Detroit Vote
Associated Press/Yahoo ^ | Dec 12 2016 | David Eggert
Posted on 12/12/2016, 7:03:02 PM by drewh
ANSING, Mich. (AP) — Michigan's elections bureau ordered an investigation
Monday into substantial ballot discrepancies in a small portion of Detroit's
voting precincts, after the discovery of a polling place where 300 people
voted but only 50 ballots were properly sealed in a container.

发帖数: 166 | 6 关于老三样，authorship, original contribution of major significance 和judge
the work of other scientist， 我的理解是这样，只要三条都被认可，申请人就会被
认为是属于本领域内的top small percentage，不会出现三条都符合，但是还算不上
top small percentage；而且，不需要三条都是top small percentage。
如果没被接受为top small percentage，基本上都是因为没能证明original
contribution of major significance。
关于original contribution of major significance，在看了很多资料后，我的理解
是这样的：
发在牛杂志上算不上证据，
单纯引用数目多效力也有限，
有效的证据如下：
1. 被非review文章引用为权威之作，高度评价；或者结果被采用，应用，重复，被当
作基础做进一步的研究
2. 被review文章详加介绍
3. 推荐信里确证了上面的两条

发帖数: 118 | 8 对不起LS.
我的问题很简单，概括的说，在有了系数(coefficients)后，如何score新data,如果是
numeric,很简单，直接带进行数据里，是categorical var就有些复杂，(1)
一个categorical var里所有level全部significant,那么也很简单，直接带进行数据里
，(2) 但如果categorical variable有部分level(s)不significant,要score一个新
data的时候，这些不significant level该取何值？
e.g.x1是categorical variable with a/b/c/d 4个levels,下面是fit model后的结果：
var estimates p-vlaue
x1 a 0.1 0.010
x1 b 0.7 0.034
x1 c 0.3 0.870
x1 d 0
x2 1.3 0.001
x4 0.08 0.002

Why
试想如果x4不significant，那么我们就用0??
如果x４ significant了，那x４是不是significant different from 0.5?
如果你发现不是了，那是不是按照你的逻辑，不用x４的estimate，用0.5？ |
|
m***c
发帖数: 118 | 10 你还是误解了。
我没有弃掉任何变量，而且model已经完成，系数已经确定(x1,x4,,,都是significant)
，这一切已经不再变动了。
在这个前提条件下，我用得到的系数来score一个新数据（比如test data）.我的问题
就在于categorical变量X1的4个值（a,b,c,d）各自都有自己的p-value,这个没有异议
吧？其中c为non-significant，在score新数据时，如果x1='a',那么x1=0.1，如果x1='
b',那么x1=0.7，如果x1='c'（这是个non-significant）时，x1=0还是0.3？
现在该明白我的意思了吧,或者你知道SCORE的意思吧，简单的说比如在logistic MODEL
里，有个score statement，这score不是要重新fit model，而只是用已经得到的系数
来拿过来算新数据的预测值。 |

这两条曲线，我们一眼看过去就觉得是肯定有区别的，因为曲线B下降的
明显比A快，而且error bar也挺小的。所以我们在文章里就很自然的说：
xxx protein in Cell B degraded significantly faster than in Cell A.
这个结论应该是没有问题的，reviewers其实也认同，因为两个曲线的差别还
是挺大的。但是，现在是主编在给我们提意见，她的意见就是当我们在文章
中作任何有关significance 的结论的时候，必须给出P value, statistical
test method. 我们一下子就被这个弄晕了。因为我们以前都是看看error bar
足够小，曲线分的够开，就大方的给一个结论的，还真的不知道怎么就两条
曲线是否有统计差别进行P value 计算。而且，我们文章中还有很多地方是
