Wait, is linear algebra not taught in HS?

2017-04-11 15:36:48 UTC  

Wasn't for me

2017-04-11 15:36:50 UTC  

Or usually, at least?

2017-04-11 15:36:54 UTC  

Gonna teach my kids it

2017-04-11 15:36:59 UTC  

i need it to do linear modeling

2017-04-11 15:37:00 UTC  

I learned it in early HS/ middle school

2017-04-11 15:37:05 UTC  

Then again I went to a private school

2017-04-11 15:37:28 UTC  

@RussianHacker like a bunch of linear equations

2017-04-11 15:37:31 UTC  

Solving?

2017-04-11 15:37:41 UTC  

Super easy

2017-04-11 15:38:01 UTC  

i need to do some proofs on why linear regression models and anovas work

2017-04-11 15:38:08 UTC  

I might have PDFs somewhere

2017-04-11 15:38:14 UTC  

and they reccomend some linear aljebra

2017-04-11 15:38:24 UTC  

Uhhhh linear regression models a little outa my league

2017-04-11 15:38:26 UTC  

What's it for?

2017-04-11 15:38:35 UTC  

My roommate might know about that

2017-04-11 15:38:40 UTC  

computational population genetics

2017-04-11 15:38:43 UTC  

Honestly the only difficult part of learning higher mathematics is the shitloads of ridiculously overcomplicated terminology

2017-04-11 15:38:49 UTC  

genomics actually

2017-04-11 15:39:25 UTC  

@RussianHacker I can tell you that a good linear algebra book should include determinants, eigenvectors and eigenvalues, characteristic polynomials, principal value decompositions and possibly least squares fitting, along with the basics like dot products and the Cauchy-Schwartz Inequality (but then, determinants are also basics).

2017-04-11 15:39:36 UTC  

Possibly other topics as well.

2017-04-11 15:39:50 UTC  

@gbol annoying, I want to know the application but I have to learn the mumbo jumbo of the definitions where they nitpick every letter

2017-04-11 15:39:59 UTC  

isnt least sqaures fitting a patial derivative?

2017-04-11 15:40:07 UTC  

optimized to zero

2017-04-11 15:40:39 UTC  

Gotta get your ridiculous english language 20 letter definitions to learn what should be pure logic @Renaar

2017-04-11 15:41:50 UTC  

@RussianHacker The equation for linear least squares fitting is beta = (X_transpose * X)^-1 * X_transpose * y.

2017-04-11 15:42:08 UTC  

oh i see, its multi variate

2017-04-11 15:42:46 UTC  

i had to do proof of this in my regressoin modeling class

2017-04-11 15:42:47 UTC  

MULTIVARIATE IS ONE WORD

2017-04-11 15:42:50 UTC  

- 10 POINTS

2017-04-11 15:42:51 UTC  

B+

2017-04-11 15:42:59 UTC  

-every college professor

2017-04-11 15:43:11 UTC  

lol if i can get C in Thoery of linear modeling class ill be happy

2017-04-11 15:43:35 UTC  

Lol

2017-04-11 15:44:17 UTC  

I feel like wrestling is simultaneously one of the best mediums for expression and at the same time the most shit

2017-04-11 15:44:24 UTC  

and I can't watch it at all

2017-04-11 15:44:29 UTC  

but it has so much potential

2017-04-11 15:44:33 UTC  

What

2017-04-11 15:44:41 UTC  

Wrestling like wwe

2017-04-11 15:44:44 UTC  

Of what

2017-04-11 15:44:45 UTC  

yeah
