Hello Ross,
Coefficient r is the Pearson Product Moment Correlation coefficient.
Linear regression is the equation for the line of best fit between the
two variables. The way I think of it correlation coefficient
(squared actually) tells you the amount of variance predicted in variable a by variable b.
If you know r you can establish the regression equation. The larger
the absolute value of r, the less the variation around that line of
best fit.
That said, I have no idea how one establishes the correlation between
systems.
Best regards,
