Stat野可唔可以問
岩岩學唔太識


即管問啦 識嘅都會盡量答 其實自己讀左4年都唔知讀左啲乜
btw支持樓主 呢啲先係高質文

唔係好明咩係random walk
知點prove Arima 010 係但 都唔係真係好明

Prior同posterior prob / random variable上堂個陣勁多prove
有時候抄唔徹又想上網睇返一係搵唔到一係就唔知學黎做咩
其實我覺得自己對呢啲冇乜sense
Proof個啲真係唔係太知用黎做乜就會記唔到
有冇方法加強

其實我唔明點解個function 做到bijection between N and S (S is countable) 就係countable

呢個唔係definition嚟㗎咩

想知點解要咁樣set個definition

嗰度最主要你要熟exponential family同識認distribution,好似係

歷史上(或者至少Cantor腦入面)一個好重要嘅問題係無限多即係有幾多
咁無限就梗係要數之不盡啦
咁點數呀
由1, 2, 3, ... 咁數囉
呢個諗法就代表住我地有一個injective function f:N→S
而countable嘅意義就係用N就數得曬,亦即係S係最少嘅無限多
咁兩個最少嘅無限多相比,就梗係一樣多
唔係點叫最少

It's now 10:30
Let's try to start

有聲既頂你

會唔會講下Partial Differentation

當年喺開頭教Archimedean property已經唔識,個proof睇到一頭霧水
2017-12-03 12:16:31
pure拎e留名
2017-12-03 12:29:52
如果當時pure你教就好
2017-12-03 15:29:46
仲記得呢堆theorm同proposition
當年份notes 200頁

Bayesian stat?
我都覺得自己對呢科冇咩sense
D notation極混亂,加上個lecturer又講得唔清晰 真係讀到頭痛

我都唔知點定義個course


Bayesian
Loss function
Two variable etc
想上網搵啲MOCC自學又冇教proof個啲

Ana唔做下題目好似冇學過咁

利申engin仔 kinli得b-

數學分析呢門學問唔做返啲exercise係好難真正明白。

咁呢樣我都幫唔到手
唔通成份exercise掉上嚟咩

有lecture pdf share仲好

btw 想聽故仔多啲

睇bartle未囉

BB班 既標準讀物梗係baby rudin 啦

想讀死me咩

Rudin做第一本analysis 其實OK

baby rudin寫撚到成pat屎咁點比初學者睇 你估係 math 55學生咩

真係懷念 依家都唔記得七七八八 剩係記得以前讀differential manifold讀到short short地

讀first course in analysis係你唔知做緊乜, 但隔年之後望返屌一聲點解自己當年咁on9

讀advance course in analysis係好辛苦終於知道自己寫緊乜
但隔年之後望返屌一聲點解自己當年咁撚勁
