今天终于有个人给我讲了个故事，我目前还没有发现问题，但是在深刻思考，看你能不
能发现。
世界上只有两个国家，美国和新西兰。
世界上也只有两个上市公司，一个在美国，一个在新西兰。
美国那个公司卖冰棍，新西兰那个公司卖雨伞。
美国冰棍公司一天销售99根冰棍，一根卖2块钱，只在太阳天卖的出去。
新西兰雨伞公司一天销售1把雨伞，一把2块钱，只在下雨天卖的出去。
太阳天和下雨天的几率50、50。
美国公司有99股股票，1股1块，总市值99块。
新西兰公司1股股票，1股1块，总市值1块。
全球市场总市值100块。
每天一结束，这两个公司就把钱（dividend）全还给投资者,然后再从新IPO。
你有两块钱投资，请问是1个公司买1股（equal weighting），还是美国公司你买1.98
股，新西兰公司你买0.02股(market weighting)，假设你可以拆分股数。
结果：
不管什么天气，equal |

for activities lasting 90 minutes or longer.
Important Tips to know:
1. Exercising 90 minutes or more per day is discouraged for people trying
to lose weight
2. Many individuals choosing to train for endurance events notice a
significant decline in weight loss and some experience weight gain due to
increased needs for specific nutrients

发帖数: 23 | 9 When you lose weight on a "diet," muscle is the first thing to go. It's more
expensive for your body to retain than fat is, so when you run low on
calories, your body dumps muscle mass and turns it into energy. When you go
off the diet, you begin to gain back the pounds - but because you now have
less calorie-burning muscle, the weight you gain is fat. By dieting, you've
effectively turned muscle into fat.
I would suggest do some weight training. Don't worry, it's very hard to get

I found a tabel of the weight of most rubbers on the market. See the table

Personally, I think the best back hand rubber is Nittaku Renanos Bright Soft
because (1) the weight is very light; (2) good balance in speed, spinning,
and control.
Surprisingly, Hurricane III with #19 sponge is also light and can be
considered as a backhand rubber.

发帖数: 3042 | 22 力量训练一般有两种途径，器械和free weight。器械相对来讲比较安全，也容易上手
，所以是大部分初学者的入门方式。用free weight虽然有很多器械训练不具备的好处
，但是因为看上去比较危险，又不是随时都可以找到spotter, 让很多新人甚至练习了
很久的人望而生畏。其实，只要严格遵循循序渐进的原则再加上common sense, 在没有
spotter的情况下也是可以很安全地用free weight进行力量训练的。
第一，Form一定要正确，尤其是深蹲和硬拉。具体的细节就是另外一个话题了。
第二，要start low, progress slow。在没有保护者的情况下，没有十足的把握，不要
尝试新重量。我一般是一个重量至少可以做6 reps x 4 sets才开始尝试新重量。卧推
和肩推新重量加10磅，深蹲和硬拉加20磅。这样基本可以保证新重量至少可以做3个，
不会出现举不起来的危险。
第三，没有spotter的时候，不要做到力竭。这个主要是针对杠铃来说的，哑铃可以比
较安全地做到力竭而不会受伤。从进步的角度看，不做到力竭肯定不如做到力竭效果好
，但是也同样会进步，只不过 |

发帖数: 4074 | 27 不知道是不是指optical reflectivity的那个plasma edge，
在该edge以下的frequency不能在材料里传播，基本上都反射
回来，而在这个frequency之上的plasma反射率大大降低。
这个plasma edge 的frequency的平方可以表示为
w^2 ~ n/m*
（具体差个什么常数记不得了，总之就是正比于carrier
density n 而反比与 effective mass m*）
这个平方就直接反映drude weight。如果材料的n不变，则这
个反映effective mass的变化；反之如果说effective mass不
变，这个则反映carrier density的变化。但是在很多材料里，
由于carrier有不同种类，很难判断carrier density和
effective mass，这种情况下，谈论这个drude weight（w^2）
就比较有实际意义。
这种optical reflectivity测量，除了研究plasma edge
（drude weight）随温度变化的情况外，还经常研究它随磁场
的变化。

发帖数: 59 | 29 先把名词用对：
是nonresponse weighting吧。
那个unresponse probability,应该是response propensity.
如果instruction没有提到race,你算response propensity不需要加入race.
如果你只是要reponse propensity,你不需要用特别的survey procdure,就用普通的
logistic就好。
你的nonresponse weights就是1/response propensity.
我不明白的是，你这是什么意思
“这个样本的取样strata是race，就分为白人和黑人两种。一共分8次取了8个小样本，
联合起来总共有1600多个observation。
我的想法是对每一个batch做unrespond weight，因为每一次取样的时候的response可
能都会不同。”
你要针对每个batch，作一次模型，然后有8个不同的response propensity的模型吗 |

请问什么时候需要使用poststratification weights？我的数据是采样了一个州的牙医
，就是想看看收取某种保险的牙医是不是有什么特点。

这种还需要不需要找来州所有牙医population的数据，来adjust age，gender什么的？
后面还要回归分析，直接把age gender什么放在predictor里面就adjusted了吧？不需

我现在在做一个包括很多国家的国际研究，碰到一个问题是感兴趣的单变量分析
correlation的系数和多元回归regression的系数方向全是相反的。regression的系数
是符合我的hypothesis的。
大概分析了一下，原因可能是美国的数据占绝大多数：总共有34000条左右的记录，美
国的数据占了超过30000条，其他国家加起来3000多条。
regression里我按国家调整了权重（weighted ols regression），做出来结果是感兴
趣的系数跟预期一样。但是pearson correlation的系数就全是反的，如果拿掉美国的
数据就没有这个问题。
我的问题是我想保留美国的数据（因为去掉美国的数据代表性就变弱了），同时让
correlation的系数和weighted regression方向一致。网上搜了一下似乎是有个
weighted correlation，但是不知道这么用在这里合不合适？用sas或者stata怎么实现
？ |
