发帖数: 7949 | 1 我们家老太太，又使好心眼儿，领了只scottish fold 回来。开始不知道是什么品种，
就觉得她长得太丑了。尤其跟我们家那只‘野猫’比起来。真是……不好看。可是这猫
特别可人疼。 会撒娇，个性好。
不知道需要什么特殊照顾不？一直给她吃和我们家野猫一样的伙食。可是她大便总是稀
乎乎的，还特别臭。而且它老流眼泪，跟受了多大委屈似的…… |

比如log 2 fold change =1就是表达量翻倍了
如果是-1，就是表达量是50%

发帖数: 46 | 12 非常谢谢ls回答我，j是什么？您是说我把10个从转了一圈的k－1个sample做出来的
model的partial likelihood加起来，这就是cross－validation的likelihood，然后呢
？怎么算prediction error？
还有，不是应该每一个fold内部先k－1组出来一个model，然后用剩下的一组validate
一下么？
抱歉我概念不太清，请教这个validate应该怎么做。。。非常感谢！! |
|
l*g
发帖数: 46 | 13 抱歉刚才点错变成回信了，请忽略！
我就是做的proportional hazard model，那么剩下那一组testing sample可以
evaluate the prediction likelihood么？怎么得到predicted likelihood呢？我是
follow一篇paper里说每一个fold里的9／10组sample做一个model，然后用stepwise来
从k个predictors里面选best model，然后用剩下的1／10组sample来evaluate the
prediction log-lik. "For each k, 把所有predicted log－lik加总得到一个score，
score越小的就越好”，没明白什么意思。。。
谢谢！ |

发帖数: 11 | 14 一个不大的数据，十几万个record， 一百个变量，用random forest作 binary
classification
因为有over-fitting, 决定用 10-fold cross-validation
做完之后，有十个 random forest Models
下一步 怎么做？
之后 是挑 validation error (on its set-aside 10th hold-out set) 最小的那个
Model吗？（需要一个final model 放进 production system）
Thanks! |
|
h********3
发帖数: 2075 | 15 Model Selection上来说，可以就这样用。挑个总共error最小的就行了。
楼上说的是一个confidence的估计。大概的意思是，你跑10个fold，可以得到10个
testing error。那么这10个error值，构成一个distribution。如果这个distribution
的varaince很大，那么说明你这个model不够consistent，跟随机的差不多，那么就没
意义了。 |

As the first quarter draws to a close, the stock market has extended its
impressive rally off the October lows with a solid 8% rise for 2012, at
least until Wednesday's selloff. Some stocks have scored extraordinary gains
of 100% and more, and for investors lucky enough to have these names, the
question now is what to do with them.
Here's how to tell.

发帖数: 868 | 45 If he had AA/KK/QQ he may raise preflop.
If he had AK he may raise after flop.
It seems he holds JT or AK (JT more likely), and in either case, you're beat
on the turn.
$205 more is a lot. I would fold. |
|
f*****g
发帖数: 15860 | 46 俺觉得不应该。
pre-flop,你BET，俺(新手)的逻辑是你一般有AJ以上或者较大pocket pair;
flop, 没人动手，你加倍，也属于正常逻辑，AJ以上的话，你凑了至少Q以上一个大对
了(J也排除了)，他跟你，显然两张对他也都有用，一张(除非拿了K)的话估计撤了；
turn，典型的check-raise，你放$55在他看来有点示弱，也显然不在乎你是一对两对，
多大对了。
呵呵，瞎猜比较可能是same hand，不过根据你以往的例子，似乎最后他也不是TJ，或
者你fold了也无从得知的。 |

what he might have is QK or AJ, that is the only possilbe hand I can beat. |
