[數撚圍爐區] Trust me, it is BASIC. (12)

話說我外國有個local都係讀數學系，佢上年變左性，明明之前都好地地。

而家係男定女？

而家係女

而家係男係女有乜所謂
又唔係搞到你

major stat 有基本數底 (U math) 想學下 UG math/ applied math有冇咩方向推薦
呢個底學 real analysis 會唔會太難? 定係先學多啲 linear algebra 好啲.. 因為我都淨係識最基本個啲 (eigenvector etc)

有乜學習目標先？

見深個啲stat 有好多數 咩principal component analysis 個啲
唔想淨係知點用 想知背後個個原理
但係又好似未夠數學水平去明咁 所以想趁得閒學番啲基本野 (最少唔會係咩都唔識咁)
好似 fourier analysis 又要番啲 real analysis 底

除非係進階理論啦，stat用的real analysis都係好基本嗰啲，反而linear algebra, matrix calculus, matrix analysis就用得好癲

接觸過 measure theory & stochastic calculus

linear algebra, matrix analysis 反而好少 想知有冇咩 intermediate lv 既topics/書推介下

matrix differential calculus with applications in statistics and econometrics唔知啱唔啱你睇
