I  have two-dimensional data, which I want to fit with a linear regression. I 
get nice results with 

[p, yf] = polyfit (x, y, 2)

And now I need the correlation factor...
Is there a nice way to calculate this?

It would be also quite good, if anybody knows how to calculate the MSWD (Mean 
Square Weighted Deviation)  for a linear regression?

Thanks!!!

Andreas
