发帖数: 36 | 1 是LD实验中碰到的问题。实验得到A,B两个量的值各10个，记为Ai和Bi， i=1,…,10.
然后定义变量C如下：
Ci=(Ai/BBar)-1, 这里BBar是mean of Bi。
请问如何计算Ci的standard error？是不是可以得到Ci的数值后直接计算这些数值的
standard error？这样BBar的variance有没有得到反映？还是应该用其它的方法？
请大家帮忙，多谢！ |

因为并不是所有数据都得这么干。如果理解了原因，LZ应该问不出这样的问题了。 |

I've used the site before several times. They arrive quickly, and the
condoms I've received all listed an expiration date of a little over 4 years
from the date of purchase, meaning they weren't sitting around for too long

发帖数: 60932 | 18 If you're like me, you took advantage of a Microsoft Technet deal a few
years ago and continued renewing in the summers since the original deal.
Last year, I "downgraded" to Technet Standard for a better price point and
just received my renewal notice for 8/31/11. After researching on here (in
a very old thread), I did some re-calculating and noticed a price drop since
the months-old post for the one-year RENEWAL of the subscription. Note,
you must currently be a member of Technet for this to... 阅读全帖 |

你不要害人害己了。
IRS不是吃素的。
就像那些假结婚拿绿卡的被移民局查到干死一样。
IRS也会查你假离婚，这个查到了，是联邦重罪， 吊销公民绿卡， 倒是你回家哭坟去
