来自主题: Statistics版 - SAS 去除leading zero的问题
我现在有个variable是character,如,
00121
0121
0122
122
AAAA
BBb
现在要把其中的数字leading zeros去掉,不管几个0都要去掉。我看了一下,如果光是
数字还是能弄的,可现在是这种混合形的,如果不能把其中的数字单独抽出来clean,怎
么做呢?

来自主题: Statistics版 - 如何处理很多的zero value?
没什么generic的方法, 如果是离散分布的, 有zero-inflated models, 不过也未必适
用于一般的数据. 连续数据就更没有什么generic的方法了.
比较naive的方法, 可以把这个问题的实际解释看成两个distribution的乘积或者合并,
一个是binary distribution, 另一个是非零情况下的连续分布, 可以分别model.

来自主题: Statistics版 - 如何处理很多的zero value?
Thanks for all the comments and suggestions. It seems mixture modeling is a
very effective way to handle this type of situation. However, not only do I
need a model for that variable to be an outcome variable, but I also need to
have the variable controlled for as a covariate in another model. In the
latter scenario, I think I still need some way to transform the variable --
is there any good way to do that? One example of the latter scenario is that
I want to create a model for the change in th... 阅读全帖

if the positive part is indeed gamma, then full distribution shouldn't be a
mixture.
however, it could be a two-part model, one for point mass at zero and the
other gamma.

We use a two stage approach, i.e. add a dummy for zero/nonzero cases,
together with the original variable.

有五个model,我们想试一下ensemble这5个model成一个,然后来跟simple average这
几个model比一下~
response就是Y,features就是hat{Y}_i, i=1,...,5
可能可行,也可能不可行,想要尝试一下。但这批数据有太多的zero,所以我对NNLS的

在想是否有什么特殊的方法可以ensemble这样的数据

Nissan has a very good lease deal on the 2011 Sentra S for November.
The interest rate is really low at 1.06% and the residual is really great at
64% for 3YR/36K. Additionally there is a $2500 incentive on the car. All
these go into making an excellent lease on this car.

http://www.dm123.cn/new/xf/2012-03-09/38373.html
再过二十多天,就要迎来春季新番的密集开播了。今年的春季新番数量多达45部以上
,且绝大部分都集中在4月上旬开播,相信届时绝对会让各路动漫迷目不暇给。随着各
部春季新番陆续敲定首播日,有关这些新番的重要情报也披露得七七八八了。近日,在
日站上就有动漫迷特意对这一季新番的声优出演情况作了一番统计。
男性声优方面,木村良平和浪川大辅在今年春季档期里接演的动画角色数量最多,
两位都将在4部新番中出演。尤其是才刚在第六届声优奖中获得配角男优赏的木村良平
,这次春季拿下的4部新番的角色大都属于主演性质,除了「黑子的篮球」的角色不算
主角,他在「坂道上的阿波罗」、「散华礼弥」和「少年同盟2」中饰演的都是男主角
,看来他今年的声优事业会蒸蒸日上了。这季接演了3部新番的声优则有入野自由、小
野友树、梶裕贵、神谷浩史、杉田智和、福山润、细谷佳正这7位。比较突出的要数小

吸血鬼猎人D
我认为这个名词代表着日本动漫制作的最高峰
可能这一点到将来很长一段时间都不会被超越
看阵容就知道了
小说是菊地秀行写的
插图是天野喜孝画的
剧场版是川尻善昭导演的
如果你对这三个完全没有概念的话
我做一个扩展
日本这些年很火的fate的原作奈須蘑菇就是受到了他的启发
从而走上了同人写作的道路,到现在这个同人团体从一个民间组织
转身变成了一个商业公司,这个公司叫做TYPE-MOON
去看看这个公司的作品,这个公司的作品有些文艺,比如空之境界,很装逼
娱乐的也有,fate zero就是娱乐
恶俗的也有,因为他本身是以写色情小说发家的,fate本来就是一个色情游戏

bout “Repulsive particle” hypothesis
Zhuang Yilong
Shanghai Institute of Science and Technology Managemen
Jiading 201800
“Repulsive particle” hypothesis is a new theory of material
action. Contrary to Newton law of universal gravitation, which explains why
an apple on the three falls to the ground, it can be called law of universal
repulsion which explains why an apple grows on the tree. It regards a plank
quantum as a material particle, which is a epulsive particle”

Stanford neuroscience research identifies more effective way to teach
abstract math concepts to children
A new study shows that students who use symmetry to learn about numbers tap
into critical brain circuits. The approach appears promising in improving
math skills in general.

来自主题: LeisureTime版 - 看 Red Tails想到了美国人民志愿军。
关于P-51 vs Zero, 可以参考下面的一番讨论:
If I had to sit in one and in a dog-fightfight, I would take the Mustang P-
51D.
"The finest of the Mustangs was the P-51D powered by a Packard built V12
Merlin which produced nearly 1,700 hp. This machine could do about 440 mph
in level flight, carried six heavy machine guns in the laminer-flow wing and
could be fitted with rockets or 2,000lbs of ordnance for ground attack
missions.
This machine when fitted with drop tanks could escort the US heavy bomber

今天无聊,看到这篇无聊的文章,就给你无聊地翻译成英文吧。
探索星系的捷径
A Shortcut to Galaxy Exploration
1. 问苍天情为何物?
1. Ask what love is heaven?
有人类的历史以来,人类就不断地探索自然,扩展了解自然的疆界。哥伦布发现新大陆
就是最好的例子。人类探索自然的勇气是从哪儿来的呢?来自人类情感的力量。那么,
情感是什么东西呢?这是千万年来,文学家探索的主题。在有一些文学家的眼中,物理
学家是没有情感的冷血动物。我就是一个物理学家。但是,我一点也不埋怨这些文学家
。虽然物理学家在自然界的探索中做出了伟大的贡献,但是,物理学家从来就没有给出
情感的物理定义是什么,也没有找到自然界蕴含情感的丝毫证据。所以,虽然人类知道
自己的生存发展跟自然环境是密不可分的,但是,很少有人类表达出对自然环境感谢的
情感。在很多人的眼中,自然界是死亡无情的物质世界。中国有一句古语,叫做“天若
有情天亦老”。因为几乎所有人类相信天是不老的,所以,认为苍天是没有情感的,就
不足为奇了。我提出了一个宇宙生长衰老的模型。虽然这个模型及其简单,能解释大多
