A two-variable regression with no intercept is given as:

Show that the R-squared ( ) for this model is equal to zero.

I think I should show that the covariance of X and Y are zero?

Hey wopashui.

There are quite a few formulas for R^2 and covariance would indeed be one way to show this. - October 31st 2012, 07:47 PMwopashuiRe: show that R square is zero

What information do you have about the model and its constraints?

No I mean the actual course material you are covering (specific topics, concepts, stuff like that).

I have no idea what that course is.
