来自主题: Statistics版 - 检验两组lift差异显著性的问题
Haven't got an answer yet? You may try likelihood ratio test (where the
reduced model assumes lift1=lift2) or wald test (you can get the confidence
interval of lift1 and lift2 and thus the ci of lift1-lift2)

来自主题: Colorado版 - 新手应该去哪个雪场?
去,我上次就是看你们搞猫狗,我也上了loveland的猫狗,lift1黑道边上那个。
尼玛开始还行,后来包太密太大,雪板转不开,摔倒了起不来,一只学版自己往下滑,
另一只被我压在屁股底下,站不起来。。。等我穿上,馒头大汉,眼睛都起雾了。滑下
去就直接累得吃饭去了。。。。

NASA has excellent websites on this

One key sentence
"The real details of how an object generates lift are very complex and do
not lend themselves to simplification"
