urgent help needed for an exam!

[azuth]

hi there, my lecturer ask me this question and i cannot solve for 2 hours



please help me!

[azuth]

how can i find r squared.. that would be enough!

[EViews Gareth]

42

[tchaithonov]

You gave him the answer to everything? Wow .. how generous of you, Gareth!

[ana06]

how was the number 42 found?

[startz]

50-8

[ana06]

and where do those numbers come from?

How is R^2 calculated from this?

[startz]

I may be missing your real question, but there's nothing to calculate. EViews displays the R-squared in the first line below the coefficient values.

R-squared 0.842328
How is R^2 calculated from this?

[ana06]

yea i know. i just need to know how that R^2 that it gives me is calculated.

[startz]

It's 1 - (sum squared residuals)/(sum squared (y-meany))
Look in the help system for "R-squared, for regression"

@Gareth: Funny.
