I curve fit some data to the equation 1/y=a+bx using a set of x, y data. I
used the 1/y form in the curve fit because I could use a linear least
squares approach. I treated 1/y as "Y" for the curve fit exercise. If I
were to use it as y=f(x), the equation is no longer linear.
Now, I need to calculate a correlation coefficient but am uncertain how to
proceed. The curve is plotted as y vs. x and that is what I want the
correlation coefficient to represent, because I'm comparing this curve fit
to another more standard equation and would like to know which fits it
better.
Any takers?
Mucho appreciated.
Mike
