[DS141] 點做 linear regression?

冇 calculus course 讀咩野雞 stat master 呀? 講嚟聽下? thesis 係咩呀? 原來你咁冇料到喎

緊係唔係啦 on9 囝
柒咗就認啦傻閪
X = QR 咁計 inv(gram(X)) 係咩呀? 識唔識呀?
inv(gram(X)) = inv(t(R)*R) 咁 QR 做 least squares 有冇計過呢個 matrix 呀? 冇呀 on9. 仲突個龜頭出嚟俾我狙擊?

我點解要大叫? 你由一個 sample 去 guess population 嘅 opinion, 證明你唔識 hypothesis testing 啦. 柒咗就認啦, 自尊心要人地去認同? 仲突個龜頭出嚟幾好笑喎, 你啲嘢錯到七彩

又迴避問題啦, 睇你個款都冇讀 robust stat 俾我拋兩句大到, 得啖笑, 冇料扮四條

economics 唔係 science 呢啲眾所周知, 你講埋唔關事嘅嘢去兜真係好笑. 你答咗我 inverse matrix 計咗喺邊先.

sdvsvsdav: 我係唔識數學同 stat, 只係睇過少少 econometrics 上嚟扮代表

"自學數學" 以為自己天才, 上連登俾巴打笑到七彩

sdvsvsdav: 唔識計 flops 同 computational complexity, 基本 algorithm fail 都做到 data scientist

sdvsvsdav 付過 7-11 二百文酒錢，憤憤的躺下了，後來想：“現在的幾流 researcher 太不成話，沒聽過 6 factors model……”

想讀下computational 啲野，有咩書可以睇下

由數步驟數量開始

上手巴寶營

我俾唔到呢方面好嘅推薦
general: 基礎 online course (algorithms) + introduction to algorithms (最出名嗰本) 或 algorithms (sanjoy, 薄啲嗰本)
numerical: 我覺得 Matrix Computations (Golub and Van Loa) 好實用
唔洗睇曬嘅, 我都係睇咗唔知有冇一半
