淺談 sdvsvsdav 心智扭曲及亞氏保加症治療方法

我冇諗到你連大路嘅 DoE 嘢都唔識, 要拎 natural experiments 嚟講啫

張六常柒野集合
有冇比以下更柒既野好想知好想知

https://lihkg.com/thread/2570146/page/2
DCF valuation 冇formal justification

https://lihkg.com/thread/3065440/page/7
ols estimator 冇計到inverse
linear regression 一定唔駛用gradient descent

causal inference 一定係structural equation model

仲有冇仲有冇

錯誤理解, 我嘅正確 statement 係, 唔洗扭曲事實仲搬個唔知乜鳩嘅人名:
Solve normal equation (to perform OLS) 唔需要計 inv(Gram(X))
普通 linear regression (OLS) 唔駛用 gradient descent
structural equation model 係 causal inference 嘅一部份
你 3 樣嘢都唔識, 仲話自己 stat degree, 可能真係野雞 degree

拗唔過人開始扭曲事實 要 cap 低先

孔乙己問人茴字點寫? 你搞掂我捉到你嘅錯處先講, 一日解決一個問題都做唔到?

本書有講Classical randomized experiment

natural/quasi experiment 同Classical randomized experiment係兩樣野黎
前者Assume Conditonal Independece Assumption (CIA) i.e., Y_0, Y_1 _|_ D | X
後者Assume Independece Assumption i.e, Y_0, Y_1 _|_ D

linear regression 一定唔駛用gradient descent

causal inference 一定係structural equation model
分唔清natural experiment 同classical randomized experiment 既分別

仲有冇仲有冇

又拋書包, 但走返去 natural experiments 度唔敢講 DoE

唔洗自欺欺人啦, 我問題你 DoE 嘢你兜到去 quasi/natural experiments, 已經證明咗你冇 stat degree, DoE 係典型嘅 stat pg course, 咁咪捉到你冇 stat training 囉

應該咁寫
list 唒佢d 柒野

econometrics 撚大戰 stat 撚時不斷遇上未聽過嘅 topics 搞到要離題 show-off 拋書包

原來係盲撚
我確實係讀stat master
你識唔識字

冇料要及早認呀 sdv乜鳩, 唔好為咗認叻繼續累積柒事

我勸你唔好再衝岀黎柒

自欺欺人, 大話講多幾次就變真話

sdvsvsdav 自稱熟 causal inference 但冇聽過 SEM

你咪唔好信囉

sdvsvsdav 扮有料周圍問人識唔識, 結果俾人問返就錯漏百出好似瀨屎咁漏出嚟

呵呵
我用sem 搵食個時你都唔知喺邊
喺holland 讀緊phd?
holland local 都唔讀自己當地既phd

比機會你上呀
仲唔威番次

都係嗰句, 你認咗我之前捉到你嗰啲錯處先.

自尊心高到唔敢認自己唔識, 只好兜到自己用嚟搵食.
你條傻閪乜都沖出嚟認自己識都幾搞笑.

自己去左holland
就睇唔起香港既柒頭
之前又話咩土炮master土炮 data scientist
那
你乞都冇撚番黎乞呀柒頭皮張六常

認咩野
你基本上冇回應我講既point
而係喺到搬龍門

開始有人惱羞成怒, 胡言亂語. 土炮都係笑你, 成個 post 都係為咗嘲笑你而設.
