歌曲 what da hook gonna be
歌手 murphy lee ft.jermaine pri

歌词
[Intro: Murphy Lee]
Hahaha, yo, yo, yo, yo
You never met a nigga like me
Yo yo, have you ever seen a little de
Who be doing what I do?
Uh huh, yo whoo!
Let's get at it dog, whoo!

[Verse: Murphy Lee]
Now what goes up, must come down (shiiett)
But we ain't comin' down, it be them same ole' clowns
Aimin' ya pound pretendin' they proud
But when you leave town they go around they runnin' they mouth (maaann)
They somethin' like a hata man
Talkin' bad about a playa as if I'm not gon' see ya lata man
You constantly frontin' until you confronted on
If you don't like what's goin' on gwoin to another song
Cause I keep a haa guilty
My cars and my money all alike man, both them filthy (get it?)
From skimpy and empty to fuel on full
See I be high when my car go Bulls
Obey no rules to school you fools
Schoolboy's err'y where, we're Young Dude news (maann)
St. Louis like Louis D. Miles and Larry Hughes
And the Young Dude done paid young des' es de

[Chorus - repeat 2x]
[JD:] But yo, what da hook gon' be (Uh oh!)
[ML:] See I don't need no fuckin' hook on this beat (Shiieet)
All I need, is the track in the background
My headphones loud, keep the blunt goin 'round and I'ma rip

[Verse: Murphy Lee]
The sun'll come out.. tomorrow
And I will never have to borrow
Got my first car when I turned sixteen
Only drove it home outta town limousines
Plus we was broke wit a deal but nobody could tell
So we did what we had to do for "Country Grammar" to sell
Haha, I stay on my own melodies
Plus I like my Booties and my Boobs like a capital letta 'B'
That's how it be, how it betta be
I preferably ratha have two or three girls in the bed wit me
Close your errs [ears] ma you ain't heard nothin' (whaa?)
I always pay ma let a brotha hold somethin'
I'm basically comin' from nothin' to somethin'
When I say nothin' meanin' pocket full of lint and buttons
(We all we got!) Used to be creative on Halloween (how you gon'?)
Stop a hotta teen went from nada to a lot of things

[Chorus]

[Verse: Murphy Lee]
People always sayin' man it must be nice
No hi no nothin' not a simple house life
Understand the money's good but I'm still from the hood
So don't be askin' for no "inch" be expectin' the "foot"
Unless you want a foot (whoo!)
I know a few crooks that can place you where you need to be put
And it might not cost me playa
Got a Benz peppa interia, paint salty playa
And we all push it, but me I push it real good
Brains blown out, chromed out, wheel real wood
Catch me on ya local derrty
Or in the studio doin' vocals derrty
I'm the same de that came through wit my crew
Let the girls do me while you do you
And um, all I need is JD beat to be bangin'
And I'll come up wit these verses that I'm usually slangin'
I be ripping man

B. Lee的女士牛仔裤，店员说是二尺六的，当然肯定没有这么大，应该是用的另外一种算法，那正规的应该是多少

LEE的裤子 分L和W ，L是腰围，W是裤长！裤长是正常计算的，但是腰围分，男款的腰围是本身号码减去8，就像（40-8=32）！女款的减7，（30-7=23），很简单，买衣服的有时候为了卖东西忽悠人，自己买东西的时候看清导购员！ 我是资深导购！给我高分啊！

F. 量化交易的第一对口专业是什么

1金融工程学2保险专业3财会。我实际感觉任何工科+数学财会都可以做量化交易：举个例子：小麦 玉米 猪肉之间如何量化转换？首先你要找一个农学家算出亩产量的概率，其次你要找一个生物学家算出营养成分 消化率 产肉率，最后你要找一个财务算出最佳投入产出比。这样一个量化交易就完成了。个人认为，跟量价相关的衍生出来的指标严格上来说都是技术指标。很多人简单的把KDJ，MACD，moving average，威廉指标等指标狭义的等同于技术分析。但是如果我在这问这么几个问题，大家也许想法就不一样了：VAR算不算技术指标？BS算不算技术指标？GARCH，ARMA，SV这类又算不算技术指标？物理里面的各类滤波转化的模型又算不算技术指标？高频里面经典的Lee-Ready算法又算不算技术指标?其实上面这些都能是技术指标，无非是有的简单些，有的复杂些罢了。即便你引入各种随机过程和非线性模型，只要是基于量价，难不成它们就不是技术指标了么？全球最大的CTA Winton和第二大的AHL发展到现在，至今他们的模型里面技术指标仍是一块非常重要的alpha来源。技术指标有没有用， 这个对于不同的量化领域确实确实会有截然不同的看法。首先，对于统计套利，有一类专门的alpha来自于量价分析，根据本人在world quant工作过的一个朋友的实战经验来看，这种alpha至今仍能在高度成熟的美国市场有一席之地；其次，对于各种套利策略，协整回归不是技术指标么？最经典的价差SD不是技术指标么？最后，回到CTA，可以说这类策略大部分都是技术指标，当然，发展至今的CTA fund，数据源已经越来越多样化了，包括现货数据，宏观数据等。但即便如此，量价策略依然占很大的比重。

G. 李氏迷宫算法的发展

迷宫算法最初是由C．Y．Lee提出的,又称为李氏算法或波扩法，其优点是只要最短路径存在，就一定能找到，然而其缺点也是明显的，对于n×n的网格空间，它需要O（n2）的运行时间和存储空间并产生了较多的层间引线孔。

C.Y.LEE简介:

William C.Y.Lee(威廉．C．Y．李)博士，国际着名科学家，教育家，近代移动通信奠基人之一。
李博士于1963年获得美国Ohio State University电气工程博士学位；1964～1979年，开创了美国贝尔试验室下的移动无线电通信研究室；1979～1985年，任美国ITT公司国防通信部的尖端技术开发部主管；1985～2000年，任美国Vodafone AirTouch公司副总裁和首席科学家。2000～2005年，任美国LinkAir通信公司董事长，现任美国Treyspan公司董事长。
李博士因开发了商用的AMPS和CDMA技术而享誉全世界，在其几十年的科研生涯中，获得殊荣无数。1982年成为IEEE会员，1987年成为全美无线电俱乐部会员，1982～1998年应美国George Washington University邀请，主讲最早的面向产业的蜂窝和移动通信课程。还有ITTDCD的技术贡献奖(1984)，Ohio State University有突出贡献的校友(1990)，IEEE VTSAvant Garde奖(1990)，美国CTIA的奖励证书(1994)，IEEE车载技术协会技术服务奖(1996)，中美(SATEC)杰出贡献证书(1997)以及贝尔试验室致力服务奖(1998)，等等。李博士还是美国国家竞争委员会的会员，美国加利福尼亚州科学技术委员会成员，北京航空航天大学、西南交大的名誉教授。
李博士为蜂窝通信领域作出了巨大的贡献。他的重要专着和教科书《无线与蜂窝通信》(1989年第1版，1997年第2版，本书是2006年第3版的中文版)风靡全球，已被翻译成俄文版、汉语版、日语版、韩语版等多种文字。在该书第1版的序言里，李博士就明确阐述了他为蜂窝通信产业制定的目标：“让我们携起手来，使蜂窝产业发挥它最大的潜力，我们的目标是：在不远的将来，让便携式蜂窝电话把我们的通话遍及世界每一个角落。”

H. lee works in the factory改为否定句

该句子改为否定句是：Lee does not work in the factory.（李不在工厂工作。）

英语句子改成否定句的方法：在动词后面加not，有is、am、are的句子会在这些词后面加not，I am(not)a boy。没有is、am、are的句子会在动词前加don't或者do not。如果有must、may、can这类的词，在这类词后面加not。根据句子的不同情况进行改动。

否定句是表示否定的句子。必须有否定词，古代汉语中否定词可以是副词“不”、“弗”、“毋”、“勿”、“未”、“否”、“非”，可以是动词如“无”。

否定句分类：

1.一般否定句

摘要

在学术界和金融界，分析高频财务数据的经济价值现在显而易见。它是每日风险监控和预测的基础，也是高频交易的基础。为了在财务决策中高效利用高频数据，高频时代采用了最先进的技术，用于清洗和匹配交易和报价，以及基于高收益的流动性的计算和预测。

高频数据的处理

在本节中，我们讨论高频金融数据处理中两个非常常见的步骤：（i）清理和（ii）数据聚合。

> dim(dataraw);[1] 48484 7> tdata$report;initial number no zero prices select exchange48484 48479 20795sales condition merge same timestamp20135 9105> dim(afterfirstclean)[1] 9105 7

高频数据的汇总

通常不会在等间隔的时间点记录价格，而许多实际波动率衡量方法都依赖等实际间隔的收益。有几种方法可以将这些异步和/或不规则记录的序列同步为等距时间数据。
最受欢迎的方法是按照时间汇总，它通过获取每个网格点之前的最后价格来将价格强制为等距网格。

> # 加载样本价格数据> data("sample");> # 聚合到5分钟的采样频率：> head(tsagg5min);PRICE2008-01-04 09:35:00 193.9202008-01-04 09:40:00 194.6302008-01-04 09:45:00 193.5202008-01-04 09:50:00 192.8502008-01-04 09:55:00 190.7952008-01-04 10:00:00 190.420> # 聚合到30秒的频率：> tail(tsagg30sec);PRICE2008-01-04 15:57:30 191.7902008-01-04 15:58:00 191.7402008-01-04 15:58:30 191.7602008-01-04 15:59:00 191.4702008-01-04 15:59:30 191.8252008-01-04 16:00:00 191.670

在上面的示例中，价格被强制设置为5分钟和30秒的等距时间网格。此外，aggregates函数内置于所有已实现的度量中，可以通过设置参数align.by和align.period来调用该函数。在这种情况下，首先将价格强制等间隔的常规时间网格，然后根据这些常规时间段内执行观察值的收益率来计算实际度量。这样做的优点是，用户可以将原始价格序列输入到实际度量中，而不必担心价格序列的异步性或不规则性。

带有时间和波动率计算的价格示例：

> #我们假设stock1和stock2包含虚拟股票的价格数据：> #汇总到一分钟：> Price_1min = cbind(aggregatePrice(stock1),aggregatePrice(stock2));> #刷新时间聚合：refreshTime(list(stock1,stock2));> #计算跳跃鲁棒的波动性指标> #基于同步数据rBPCov(Price_1min,makeReturns=TRUE);> #计算跳跃和噪声鲁棒的波动性度量> #基于异步数据：

实际波动性度量

高频数据的可用性使研究人员能够根据日内收益的平方来估计实际波动性（Andersen等，2003）。实际上，单变量波动率估计的主要挑战是应对（i）价格的上涨和（ii）微观结构噪声。因此多变量波动率估计也引起了人们的注意。高频软件包实施了许多新近提出的实际波动率方法。

下面的示例代码说明了日内周期的估计：

> #计算并绘制日内周期> head(out); returns vol dailyvol periodicvol2005-03-04 09:35:00 -0.0010966963 0.004081072 0.001896816 2.1515392005-03-04 09:40:00 -0.0005614217 0.003695715 0.001896816 1.9483792005-03-04 09:45:00 -0.0026443880 0.003417950 0.001896816 1.801941

Frost 滤波算法

例句：
Different sizes of filtering windows,from 3×3,5×5,7×7,to 9×9(pixel×pixel),were used in some useful filtering methods such as （Kuan algorithm,Frost and Enhanced Frost algorithm,Lee and Enhanced Lee algorithm）. Several cases of filtering performance were compared and studied based on different indexes.
选择Kuan、Frost与增强Frost以及Lee与增强Lee等滤波算法,分别采用3×3、5×5、7×7、9×9及11×11(像元×像元)等大小的滤波窗口进行处理,以常规图像统计参数、平滑指数和边缘保持指数等为评价指标,对滤波效果进行定量比较。
