This has already been discussed here, cf.

0  g [y^, r] => intercept
1  g [y^, r] => slope + intercept

So this...
y^, r
y^, r

...returns the y-intercept in X, the slope in Y and the correlation coefficient in Z and T.

Also post #8 in that thread has essentially the same program as Gamo's, just without the double calculation of the determinant.

Note: Gamo, I have sent a PM earlier today as you originally posted this to the Articles forum where no replies are possible.
