• ......Damn.
hey sorry, was contemplating.
• Nah it's cool, I've been trying to get some new vocabulary down. Having a hard time with that. xP
• Jeeshan Hot Shot
hey d00d
i see. japanese vocab?
• Yeah, Japanese.

Heya, Jeeshan.
oh oh oh! least squares regression, it came to me. i remember that. its fun.
• It's fun..? I'd use a different descriptor lol I honestly don't get the formulas for it.
finding slope and intercept, right? y=mx plus b?
• Jeeshan Hot Shot
lol i have those s--- in my adv maths textbook
• Yeah, you need to use slope, but in this instance slope= r( standard deviation of y divided by the standard deviations of x)

I need to find predicted y which equals a+bx where apparently a = mean of y - b times the mean of x

ugh I hate math
• Jeeshan Hot Shot
sometimes i feel like im complete stupid.
feel-stupid increased to lvl 100.
can you give me what the question says specifically?
• I'm prepping for a test, don't really have any questions. Just need to get formulas down... and terminology. The formulas/ equations I need to get are LSR and the residual formula.

Maybe I can find some questions in my book

Yeah, math does that. I bet it increases stupid waves
i did some thinking. so are you all set with this part?

add up x and y. then for each sum find the σ with SR(#-M)^2
b= r [σ(y/x)] and a= - b(x)
