FitPow( <List of Points> )
Calculates the regression curve in the form a xb.
Example: FitPow({(1, 1), (3, 2), (7, 4)}) creates the regression curve f(x) = 0.97 x0.71.

FitPow( <List of Points> )
Calculates the regression curve in the form a xb.
Example: FitPow({(1, 1), (3, 2), (7, 4)}) yields 0.97 x0.71.
