    oh oh oh! least squares regression, it came to me. i remember that. its fun.
  • avatar
    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?

    lol i have those s--- in my adv maths textbook
  • avatar
    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

    sometimes i feel like im complete stupid.

    can you give me what the question says specifically?
  • avatar
    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)
