歌詞
[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的女士牛仔褲,店員說是二尺六的,當然肯定沒有這么大,應該是用的另外一種演算法,那正規的應該是多少
LEE的褲子 分L和W ,L是腰圍,W是褲長!褲長是正常計算的,但是腰圍分,男款的腰圍是本身號碼減去8,就像(40-8=32)!女款的減7,(30-7=23),很簡單,買衣服的有時候為了賣東西忽悠人,自己買東西的時候看清導購員! 我是資深導購!給我高分啊!

F. 量化交易的第一對口專業是什麼
1金融工程學2保險專業3財會。我實際感覺任何工科+數學財會都可以做量化交易:舉個例子:小麥 玉米 豬肉之間如何量化轉換?首先你要找一個農學家算出畝產量的概率,其次你要找一個生物學家算出營養成分 消化率 產肉率,最後你要找一個財務算出最佳投入產出比。這樣一個量化交易就完成了。個人認為,跟量價相關的衍生出來的指標嚴格上來說都是技術指標。很多人簡單的把KDJ,MACD,moving average,威廉指標等指標狹義的等同於技術分析。但是如果我在這問這么幾個問題,大家也許想法就不一樣了:VAR算不算技術指標?BS算不算技術指標?GARCH,ARMA,SV這類又算不算技術指標?物理裡面的各類濾波轉化的模型又算不算技術指標?高頻裡面經典的Lee-Ready演算法又算不算技術指標?其實上面這些都能是技術指標,無非是有的簡單些,有的復雜些罷了。即便你引入各種隨機過程和非線性模型,只要是基於量價,難不成它們就不是技術指標了么?全球最大的CTA Winton和第二大的AHL發展到現在,至今他們的模型裡面技術指標仍是一塊非常重要的alpha來源。技術指標有沒有用, 這個對於不同的量化領域確實確實會有截然不同的看法。首先,對於統計套利,有一類專門的alpha來自於量價分析,根據本人在world quant工作過的一個朋友的實戰經驗來看,這種alpha至今仍能在高度成熟的美國市場有一席之地;其次,對於各種套利策略,協整回歸不是技術指標么?最經典的價差SD不是技術指標么?最後,回到CTA,可以說這類策略大部分都是技術指標,當然,發展至今的CTA fund,數據源已經越來越多樣化了,包括現貨數據,宏觀數據等。但即便如此,量價策略依然占很大的比重。
G. 李氏迷宮演算法的發展
迷宮演算法最初是由C.Y.Lee提出的,又稱為李氏演算法或波擴法,其優點是只要最短路徑存在,就一定能找到,然而其缺點也是明顯的,對於n×n的網格空間,它需要O(n2)的運行時間和存儲空間並產生了較多的層間引線孔。
C.Y.LEE簡介:
William C.Y.Lee(威廉.C.Y.李)博士,國際著名科學家,教育家,近代移動通信奠基人之一。
李博士於1963年獲得美國Ohio State University電氣工程博士學位;1964~1979年,開創了美國貝爾試驗室下的移動無線電通信研究室;1979~1985年,任美國ITT公司國防通信部的尖端技術開發部主管;1985~2000年,任美國Vodafone AirTouch公司副總裁和首席科學家。2000~2005年,任美國LinkAir通信公司董事長,現任美國Treyspan公司董事長。
李博士因開發了商用的AMPS和CDMA技術而享譽全世界,在其幾十年的科研生涯中,獲得殊榮無數。1982年成為IEEE會員,1987年成為全美無線電俱樂部會員,1982~1998年應美國George Washington University邀請,主講最早的面向產業的蜂窩和移動通信課程。還有ITTDCD的技術貢獻獎(1984),Ohio State University有突出貢獻的校友(1990),IEEE VTSAvant Garde獎(1990),美國CTIA的獎勵證書(1994),IEEE車載技術協會技術服務獎(1996),中美(SATEC)傑出貢獻證書(1997)以及貝爾試驗室致力服務獎(1998),等等。李博士還是美國國家競爭委員會的會員,美國加利福尼亞州科學技術委員會成員,北京航空航天大學、西南交大的名譽教授。
李博士為蜂窩通信領域作出了巨大的貢獻。他的重要專著和教科書《無線與蜂窩通信》(1989年第1版,1997年第2版,本書是2006年第3版的中文版)風靡全球,已被翻譯成俄文版、漢語版、日語版、韓語版等多種文字。在該書第1版的序言里,李博士就明確闡述了他為蜂窩通信產業制定的目標:「讓我們攜起手來,使蜂窩產業發揮它最大的潛力,我們的目標是:在不遠的將來,讓攜帶型蜂窩電話把我們的通話遍及世界每一個角落。」
H. lee works in the factory改為否定句
該句子改為否定句是:Lee does not work in the factory.(李不在工廠工作。)
英語句子改成否定句的方法:在動詞後面加not,有is、am、are的句子會在這些詞後面加not,I am(not)a boy。沒有is、am、are的句子會在動詞前加don't或者do not。如果有must、may、can這類的詞,在這類詞後面加not。根據句子的不同情況進行改動。
否定句是表示否定的句子。必須有否定詞,古代漢語中否定詞可以是副詞「不」、「弗」、「毋」、「勿」、「未」、「否」、「非」,可以是動詞如「無」。
否定句分類:
1.一般否定句
I don't know this. No news is good news.
There is no person(smoking)/not a person/not any person(smoking)in the house.
2.特指否定
He went to his office, not to see him.

I. 什麼是波動率指數

摘要
在學術界和金融界,分析高頻財務數據的經濟價值現在顯而易見。它是每日風險監控和預測的基礎,也是高頻交易的基礎。為了在財務決策中高效利用高頻數據,高頻時代採用了最先進的技術,用於清洗和匹配交易和報價,以及基於高收益的流動性的計算和預測。
高頻數據的處理
在本節中,我們討論高頻金融數據處理中兩個非常常見的步驟:(i)清理和(ii)數據聚合。
> 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
高頻數據的匯總
通常不會在等間隔的時間點記錄價格,而許多實際波動率衡量方法都依賴等實際間隔的收益。有幾種方法可以將這些非同步和/或不規則記錄的序列同步為等距時間數據。
最受歡迎的方法是按照時間匯總,它通過獲取每個網格點之前的最後價格來將價格強制為等距網格。
> # 載入樣本價格數據> data("sample");> # 聚合到5分鍾的采樣頻率:> 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秒的頻率:> 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,價格被強制設置為5分鍾和30秒的等距時間網格。此外,aggregates函數內置於所有已實現的度量中,可以通過設置參數align.by和align.period來調用該函數。在這種情況下,首先將價格強制等間隔的常規時間網格,然後根據這些常規時間段內執行觀察值的收益率來計算實際度量。這樣做的優點是,用戶可以將原始價格序列輸入到實際度量中,而不必擔心價格序列的非同步性或不規則性。
帶有時間和波動率計算的價格示例:
> #我們假設stock1和stock2包含虛擬股票的價格數據:> #匯總到一分鍾:> Price_1min = cbind(aggregatePrice(stock1),aggregatePrice(stock2));> #刷新時間聚合:refreshTime(list(stock1,stock2));> #計算跳躍魯棒的波動性指標> #基於同步數據rBPCov(Price_1min,makeReturns=TRUE);> #計算跳躍和雜訊魯棒的波動性度量> #基於非同步數據:
實際波動性度量
高頻數據的可用性使研究人員能夠根據日內收益的平方來估計實際波動性(Andersen等,2003)。實際上,單變數波動率估計的主要挑戰是應對(i)價格的上漲和(ii)微觀結構雜訊。因此多變數波動率估計也引起了人們的注意。高頻軟體包實施了許多新近提出的實際波動率方法。
下面的示例代碼說明了日內周期的估計:
> #計算並繪制日內周期> 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

J. The Frost algorithm 這是什麼演算法要通信專業術語。
Frost 濾波演算法
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.
選擇Kuan、Frost與增強Frost以及Lee與增強Lee等濾波演算法,分別採用3×3、5×5、7×7、9×9及11×11(像元×像元)等大小的濾波窗口進行處理,以常規圖像統計參數、平滑指數和邊緣保持指數等為評價指標,對濾波效果進行定量比較。
