I need to count the unique values in one column in EXCEL 2010.
The worksheet has 1 million rows and 10 columns. All cell values are string
or numbers.
I used the solution at Count unique values in a column in Excel
=SUMPRODUCT((A2:A1000000<>"")/COUNTIF(A2:A100000,A2:A1000000&""))
But, it runs so long time that the EXCEL is almost frozen. And, it generates
25 processes in Win 7.
Are there more efficient ways to do it ?
Also, in the column, all values have for format of
AX_Y
here, A is a chara... 阅读全帖

来自主题: Statistics版 - Expected value 和 std难题求教
准备面试的时候,看面经发现一道以前的概率题,完全不知道怎么做。现在求助版上的
大神。
题目如下:
1. 基本问题。一个数据流包含4个整数,每个整数随机分布在1到10之间,两端都
包括,每个数的概率是一样的(即都是十分之一), 这个数据流会被一个函数处理,
这个函数会保留这个数据流里面最大的两个数,并且返回这两个最大数的乘积。 假设
这个函数会处理很多这样的数据流,请问这个函数返回的乘积的expected value和 std
是多少?
举几个例子:
第一个数据流 包含8,4,9,2。最大的两个数是8和9,返回72.
第二个数据流包含10,2,5,10,最大两个数是10,10, 返回 100.
。。。。。。以此类推
先说说我的思路。如果这个题不是问乘积,而是问最大值的expected value,就变得比
较简单。
要算最大值的expected value, 可以用下面的方法。
假设最大值是k,那么k是最大值的概率为(k^4-(k-1)^4)/10^4。也就是说要k是最大值,
这个数据流里面的每个数都只能取1至k,总共有k^4取法。但是还要去除某些不包含k的
组合,这些组合有(k-... 阅读全帖

标 题: 车祸请教: 保险公司拒绝赔偿"Diminished Value"怎么办
发信站: BBS 未名空间站 (Thu Feb 23 18:30:49 2012, 美东)
上个星期, 车子被一个同事在停车厂里撞了, 因为比较严重, 没法私了, 就报了保
险公司。
首先让我生气的damage estimate, 我想拿一笔就走人, 这车我根本不想修理, 即便
我花一百万美金修车, 这辆车早晚会年旧报废。 但是保险公司只答应直接给我$2000
,如果修车不够, 让修车行找保险公司“商量”或“索要”。可是我并不打算修, 只
想拿钱走人。 我去了几家body shop, 普遍估价$3000以上。
其次,保险公司(Amica)拒绝赔偿"Diminished Value"。我车是accident free的新车,

车的value体现为utility value和driving experience value,更看中utility value
的就会倾向suv,同时也具备一定的driving experience value,当然是和van相比。但
是suv的驾驶体验跟小车比还是差远了,把驾驶体验追求到极致的超豪华品牌是不会屑
于搞个suv的(脑袋被驴踢了的蓝宝除外哈)。所以你绝不会见到有人开911做commute
,然后搞个差五做weekend fun car。就个人经验,suv中驾驶感觉能媲美小车的除了卡
宴,找不出别的了。象差五之类,即使是sport activity trim,315宽的后胎,过弯道
也没有什么信心。

重看了下, 你的问题好像没说清楚
不过试试用Chained Hash了吗?
1) create the hash table.
2) create a link-list node that stores the position of the value
3) put the values inside the hash table. Preferably, during insertion,
you want LIFO
4) loop thru the array again
4.1) get hash[sum-value]
4.2) print if the position of the hash value is greater than current
value's position.
4.3) if position > node->position, continue;

appraisal的报告上,有一项是估出来的房子本身的价值(通过跟其他的comp比较)。
另一项是直接引用county的propery tax里的land value(就是地值多少钱)。
你想,appraiser是不知道地值多少钱的,所以他必定引用那个数字。
所以,现在正在卖房子的,就不要去appeal你的property tax了,因为buyer都会去查
的。
好比说,你的房子本身market value应该有40万。你当初买来是个好deal花了30万。
之后,你又appeal,county也给调整到30万,county调整的方式之一就是降低land
value.
精明的buyer会像appaiser一样,把房子的value+land value,估算出你房子的价值,
明显很容易低于40万,所以你就卖不到一个deserve的市场价。

刚收到银行对要买房子的Appraisal, value 居然和我们的成交价一样。
可之前我们的agent,不停的对我们说什么Appraisal value 肯定会比我们的成交价高
非常多,因为我们买到了最好的super good deal 啊什么的,还到处对别人包括对home
inspector说,到后来听得我们很烦好像我们捡了个天上的大馅饼似的
这闹了半天我们也就是出的market value,现在看见市场上房子还在一直跌,感觉心里
还是挺郁闷的,况且我们买的这个20年的房子几乎从没做过upgrade,搬进去还要花不
少钱,觉得当时应该再压一下价格的,可是脸皮太薄了
请问大家当时买房子时,银行的Appraisal value 和你买的价格差的多吗,是不是银行
趋向于把Appraisal value往成交价上靠呢?
感觉还没最后close呢,我这buyer's remorse 就已经开始了

现在还在租房,是 condominium,看到市政的财政部发的notice of property value,
对里边几个东西搞不懂,market value, actual assessed value, transitional
assessed value, 不知道交地税的是凭哪个value?
而且我看这个数字都偏低,价值只有现在目前市价的1/10, 比若说,在notice列出来
的都只有$40k左右,但是现在挂出来的市价大概是$450k左右,搞不懂notice的数字怎
么来的。
但是估算的租金倒是没有差那么多,只差了$500左右,也搞不清这个rent是如何推算出
来的?
而且若买下这个租的房子的话,那时候交税时按照$450k左右算,还是按照$40k左右算?
多谢指点了,龙年大吉。

What you get is the assessed value, which is what the property taxes on your
home will be calculated on. Oftentimes market value is much diffent.
Market value is the most probable price at a specific date if you
voluntarily sell your house. The assessed value is the market value times a
ratio. This ratio is different from town to town.

For the most part, 529 plans offer mutual funds as investment options. After
the financial crisis in 2008-2009, many 529 plans added more conservative,
guaranteed principal options offered by banks and insurance companies.
Because money in 529 plans is typically long term, these guaranteed
principal options sometimes offer attractive yields. They can be a better
deal than bond mutual funds because they don’t have interest rate risk.
These guaranteed principal options are especially goo... 阅读全帖

一帮不懂的人在那里瞎说!
Stock的市场价值等于future cash flow discounted to the today at a certain
discount rate是没错,就是市场认为这公司值多少钱。
equity = book value = asset-liability,这也没错,其实就是今天公司的清算价值
,把公司所有资产变现,把所有负债还掉,剩下的就是股东的钱,就是equity。
至于par value,是法律上规定,每一股在发行时股东至少要付进来的钱,但是法律对
最低付进来的钱并没有最低额度限制,所以就出现了0.01,0.001每股par value的情况
。公司发行股份就是卖股份,不管是引进战略投资者,IPO发新股,还是award给高管,
公司至少得收到每股par value的价值;由于这个数字可以极低,也就给员工股权激励
,或者业绩对赌输股票等需要接近于0成本发行股票的情形制造了便利。这就是一个单
纯的法律规定,股票不能免费给,交换就必须有对价,否则就是gift。这就是这个个
par value的意义。

最后一句话不对。
理论上,董事会作为公司的最高管理机构,可以以任何价格发行公司股份,但有两个硬
性限制,一个是公司章程规定的总可发行股份数(超过的话,需要先修改公司章程才可
以),一个就是每股发行价格不得低于par value。
但是董事会是不能随意行事的,董事会必须以公司利益最大化行事,即business
judgement rule。如果是员工股权激励范围内的par value发行,或者其它公司履约情
形下的par value发行,则不会违反上述规则;如果是引进战略投资者,或者IPO发行新
股,或者其它商业交易有关的股票发行,则必须按市场价格,否则属侵害股东利益,股
东可对board提起class action。
这就是为什么,有时按par value发行,有时按市价发行的根本原因;但是任何发行都
不得低于par value。

去年2M买的房子,刚收到county 的估价
估了150k 的improvement value
和 1.85M的land value!!!
2000sqft的房子,improvement value也估得太少了。
我的理解:
improvement value越多,以后作为出租房,可以报的depreciation越多,所以越多越
好。
land value估得多,没啥好处。
请问我的理解多吗?能跟county去argue吗? 谢啦

来自主题: Statistics版 - proc logistic遇到missing value怎么处理
1)because in data, SAS does not think the value is missing. for example, if
the variable is character, then blank (string with zero length) is
different from missing. if you have a value representing missing, then
certainly it is not missing.
2) By default, SAS will fit the model without records with missing value. I
don't know whether SAS has a mechanism to impute the missing value
automatically in the procedure. But SAS does have some procedure to impute
missing values.(I forgot the procedures

想在此问一问大家, 有什么方法可以用macro来修改format value的值. macro的parameter里有format name.
举个例子
比如我有一个variable是cityname, 他的对应format 是这样的
value city
1='1. Beijing'
2='2. Shanghai'
3='3. Tianjing';
现在我想作的是用一个macro来调出cityname对应的format, 然后把单引号里面的值稍作改动, 变成
value city
1='Beijing'
2='Shanghai'
3='Tianjing';
就是把最前面的数字去掉了. 我在网上搜了半天, 没有发现有什么sas function可以去
提取format value的值. (如果能够提取那个值, 修改值就用compress()之类的function就可以简单完成了. )
请哪位高手指点一下.
谢谢先

Newt Gingrich is smarter than you. Don't feel bad, he's smarter than

Dennis Prager thinks Americans are in danger of forgetting their core
principles, so he’s out to remind them what’s important.
“American values are the greatest single value system that has ever been
devised,” nationally syndicated radio host and columnist Prager told

标 题: 你们阿都没有搞清楚啥事interest, 啥事value
发信站: BBS 未名空间站 (Sat May 21 10:16:40 2011, 美东)
在interest免前, value不过是遮羞布
美国自己坦然承认在interests面前可以践踏,对他们用的就是践踏这个词
他们鼓吹的values
当然values也可以当作争夺 inerests的接口

来自主题: Automobile版 - diminished value
车被撞,对方全责,找对方保险公司索赔diminished value
对方从最开始认赔600,到1000。然后我提供了KBB对车撞前的估价,车的维修价格和网
上的第三方评估diminished value,评估出来大概是3300的diminished value。
这些证据提供了之后,对方认赔到1500.
请问还要如何争取才能要回第三方评估的3300 diminished value?需要上小法庭么?
