来自主题: Statistics版 - 答水泡泡:陈立功是谁教出来的?
下面是ohyoo (kk) 和drburnie在全部讨论中提出的最强烈的质疑,因而也是最具挑战
性的问题。我想我有必要回答他们俩的问题。
1. 为什么不可以假设(assume)Continuity: 回答很简单。这个假设没有概率论支持
,意味着整个方法论没有得到概率论的支持。因此,有必要将那个assumption改为一个
hypothesis,从而使得整个方法论得到概率论的支持。
2. 由于连续性不可假设,因而通过解联立方程组得到临界点的估计的方法就不可行,
从而必须另寻它途。
3. 无论是从统计学本身的角度,还是从方法论被应用的领域的角度,都无法事先确定
临界模型是连续的或不连续的。唯一的途径是从概率的角度对连续性作出推断。
4. 如果smoothness必须要做,则也只能在连续性检验的基础上做。如果检验结果不支
持连续性,则smoothing是不可以的。其实,从统计的角度,如果采用了连续性检验,
则是否进一步从数学上、统计图形上搞出一个smoothy的结果意义已经不大了。
5. 在多维空间里,smoothing是极其困难的。

Hi, hezhi,
你终于现身了。你曾经和我认真地讨论过一些问题,我也非常的感激。现在,我被鄙被骂
得够呛。中国同胞够厉害啊!个个都毫不留情,痛下杀手。
好在,我是“非凡”的,不会理会那些屁话,它们也伤不到我一根毫毛。
关于5,请原谅在我仅仅是一个直觉。我没有理论。不过,显然,到了4维及以上的空间
里,我们就看不到smooth的图形了,即使一个人声称他的处理结果一定是smooth。当
然,我不能排除能够从数学上搞个证明过程说那个处理是smooth,不过,好像也没人能
够证明说一个算术平均数就是最好的。因此,我怀疑这样的证明是否有效?是否有意义?
逻辑通不通,还请大虾帮助纠偏。呵呵。

You can use the following 4 methods to do forecasting for a short time
series.
My previous boss (MBA degree)always asked this kind of questions: to predict
next 1 or 2 points with 7 or 8 time points. Believe or not, sometime it
worked very well.
1: Moving averages
2: Forecasting using exponential smoothing
3: Accounting for data trend using Holt's smoothing
4: Accounting for data seasonality using Winter's smoothing

在过去两年的自由泳学习过程中,我听到的建议都是头要低,收下巴,眼睛看正下方,
“swim downhill”,头低了,腿就浮起来了,减少阻力。
直到上周跟高阳游泳时,他给我指出我的头太低了,造成头一上(换气)一下,反而增
大了阻力。建议我头可以高一些,水面刚好高过眉毛就行了,这样游开水时也更容易换
气。我说那腿会不会沉得更厉害?他说等你打水练出来了下身自然就浮起来了。
于是我试了试把头抬高些,看pool的斜前方,好像的确游得更流畅些。

本来想写个简短的回复帖,结果越写越长,就单独贴在这里和一和。
要了解美国资本家行为的复杂性,这里必须从美国人的欧洲文化传统, 尤其是其清教徒

新教伦理(现在美国占主导地位的福音教派伦理体系)非常好地解决了所谓的“ANIMAL

来自主题: Automobile版 - 我的买旧车经验。
版上有不错的经验介绍。
但是感觉不够突出重点。
我根据他们的建议,查了很多项,
感觉头大,一时间还有些照顾不过来。
有些重要的东西反而忽略了。
我觉得车有3个重要的东西。
发动机,离和器(manual or auto transmission),车的底盘或者骨架。
油汪汪的发动机旧不要看了,漏一点油还可以考虑。
发动机的冷却系统不能漏。不然发动机很容易烧掉。
发动机开启来马力要强,不能有大的噪音。但是老车不能太强求。
auto transmission静止下换党,要smooth。不能有咯噔咯噔的动静。
(这一点我买车时没注意,如果注意到了当时至少可以侃侃价)
开启来,慢加速和快加速也要尽可能smooth.不能有很大的失速的感觉。
车子不能有大的车祸。如果车祸伤到骨架,高速下回很危险。
我的经验是看门,后被乡,引擎盖的接逢处是否对不齐。
引擎盖下的螺丝是否换国。如果有,说明车子可能有车祸,
不然不会换这些东西的。

这个周末试驾了新款x3 28i和11款Q5 2.0T和3.2。感受如下:
先说x3: 有点失望。。。自己以前有一辆07款的x3,感觉新款的比以前的轻了不少,
但是开上去反而失去一定的稳重感。发动机力度有点不足,可能35i要好很多,但是有
点怕HPFP的问题。
优点: 内饰比以前好太多,NAV改进不少,后备箱空间充足,整个一个小x5.
缺点: 太贵,有点over price。 BMW现在虽然号称比以前便宜2000,但是基本把以前
有的standard的都加成option了。驾驶感觉相当一般,可能35i要好些。
Q5: 2.0T的就不谈了,没可比性,感觉比较差劲。 说说3.2的。 3.2的驾驶感觉太棒

开肌肉车跑车就别追求smooth了,设计的时候smooth就不是priority..
咬合快才是王道。不过有可能我是错的,我也没开过那么多车,你再去试试其他肌肉车
或者跑车就可以下结论了,别跟aveo,passat比

样。

这里不说corrolla,倒是不知道focus为啥这么多人捧,最近刚租过一个才开了几千
miles新款focus,顶配,皮椅天窗,整个旅程开了上千miles,东部的地形稍微有点起
伏,上个坡就轰鸣,动力不强,发动机不smooth,倒是几个月前租的kia forte,也是
才开了几千miles的新车,开起来感觉很不错。加速相对smooth。几年前租车拿个也是
顶配皮椅天窗才开了几千miles的taurus,内外做工那个糙啊,一个六缸车,可能因为
本身重吧,加速一点没优势。坦率说,我对ford没啥好感,同样开过的车chevy俺就感
觉还不错。
版上如此吹捧ford,不知道是真觉得ford好呢,还是为了反日而反日,如果要反日,我
看还是去买VW好啦,新车passart俺试过,质量好不好我不知道,但是新车开起来感觉
的确好,真正比两田强,当然也比两田贵几千。
所以lz还是自己去试试车好!

来自主题: Automobile版 - Camry新车transmission问题
2011的camry新车,才开了2000mile左右,虽然买的时候就感觉到这车的6-speed
automatic transimission很喜欢自己调档,加速跟减速都能感觉到这个transimission
不算太smooth,但觉得这车普遍都这样,就没太介意。
但近来仔细感觉了一下,发现在高速的时候,如果踩油门之后松油门松得过快,一下子
抬脚,就能感觉到车子顿挫了一下,试了很多次都会这样。local的时候,偶尔在低速
下踩油门加速的时候,也能感觉顿挫的一下。
请教这是transmission出问题的症状吗?会可能是什么问题引起的?如何跟dealer的
service technician描述这一问题?car jerking? shaking?说transmission not
smooth的话我怀疑dealer会说这不算问题,是普遍现象敷衍过去,虽然这检查应该算
warranty cover的,但听说dealer对新车出小问题总喜欢敷衍了事。
谢谢了。

有点长,不好意思,捡感兴趣的看吧。前后试驾了Q5,SRX,LR2,X3,MDX和ML350。
先说品牌,国人比较看重这个,这里只说中国人心目中的品牌价值,在美国都只不过是luxury car,没区别。。。原来在国内和一堆懂车的人打过交道,对于三辆徳车普遍的认识是,MB:10,BMW:9,Audi:7。现在在国内车坛也基本是这个评价。Cadillac,Land Rover和Acura都属于小众车,感觉还没有形成价值体系,只不过Landrover这几年势头很猛,在中国买的最好,号称男人的车。。。不过国内要买路虎的都是买Range Rover,买LR2的很少。。。。
其次外形,外形就像女人一样,一旦倾心,很多时候便无法自拔,你要真是特别喜欢一款车的外形,下面的内容大可不必看了。。。毫无疑问,Q5是最讨亚洲人欢心的,圆润的脑袋和屁股,两侧没有什么太多棱角和线条,简单干净,从车版关注Q5的帖子数量就可见一斑。这几辆车里面最对我口味的是SRX和ML350,比较喜欢鲜明的线条和轮廓,纯属个人口味;Q5的头我很喜欢,就觉得屁股被切掉一截,不舒服。
说说试驾:

来自主题: Automobile版 - 2012 ford focus有木有人买?
你买的什么trim?多少钱拿下的?我看truecar.com上的target价钱基本上是9% off
MSRP,也就是invoice减1000左右,不知道还能不能再低点。
看网上的论坛,这车被人诟病最多的是Myford touch,反应慢,容易死机,不过据说今
年第一个quarter ford要发布个大的更新会fix大部分问题。另外一点就是双离合变速
箱,低速下不smooth,据说放在S档开会有改观。这个我倒不是特别介意,毕竟这东西
本质是手动挡变速箱,让人来换挡的话低速也不容易smooth。你说的这个噪音倒还没听
说过。

honda cars live to their fame.
i have drive civic and accord. Both were used cars but they are super reliable.
However, it does not mean every honda car is reliable.
As a matter of fact, not every car is made equal.
You have to test drive.
I took me 10 tests to find the first civic. I put on 150 K mile without any problem.
I test-drived 5 accords before buy it, I put on 50 k so mile without any sign of problem.

早晨去了BMW Dealer 试车, 稍微谈谈感受吧。
据Sales 讲这家 Dealer 号称是全美最大的BMW Dealer, 比一般的Dealer 大10倍,
Loaner Car 都有近200辆。 每月卖出400多辆车。
旁边的 Jaguar Dealer 关门了,被他们买下来,改成了 卖 Mini cooper 的 dealer,
紧邻的 Audi 和 Volkswagen dealer 同 这家 BMW Dealer 是同一个 Owner。 TNND,
偶在想,这Owner 得多有钱啊。
言归正传,由于时间的关系,偶只试了四辆车,按顺序是
1. 2012 X3 35i
2. 2013 X3 28i
3. 2012 X3 28i
4. 2013 X5 35i
1,X3 35i当然最好,动力强劲,Turbo 声音较大
2. 2013 X3 28i 用的是 新的 N20 Engine, 动力 / 加速比 35i 明显要弱,速度起来
较慢,Turbo 声音比较明显。新的Engine start / stop 功能比较有意思,在等红灯的
