Derivation of the Chi-Squared Distribution [ Statistics Basics I Studied #5 ]

OK so now it’s the chi-squared distribution’s turn. The chi-squared distribution is one of the gamma distributions with parameters (α, λ). It…

Derivation of the t-Distribution (Student t-Distribution) [ Statistics Basics I Studied #6 ]

First off, the reason this thing is called the student t-distribution is that W.S. Gosset, who worked at a certain brewery…

Derivation of the F-Distribution [ Statistics Basics I Studied #7 ]

And this time it’s the F distribution — the last of the bunch. The reason we hit the F distribution right after the t-distribution is that the statistic T follows the distribution…

But — even going through it all again, I keep getting this feeling that I’m just really, really weak at stats…..

Maybe I should go back to square one and dig into probability theory properly…

For probability theory, people recommend Sheldon Ross.

For mathematical statistics, they say Hogg —

are there any other bible-tier books out there?????? Anyone?

For now I’ve tossed them in the shopping cart, but….

In October my weekday evenings are booked with a machine learning course after work, and weekends I’m in a pandas course……lol lol lol lol

And then there’s like right now — Saturday, parked in a café grinding through the accounting principles course…… (which I still haven’t finished… seriously…. (T_T))

In between all that I’m doing some coding for fun lol lol lol lol lol, I really wanna try some FDM in Python… heh.heh

Why is a day only 24 hours………?

Then again, if a day were 36 hours I’d probably have already worked myself to death, right?
