I have a multivariable exponential function (Y=kA^aB^b...) that I would like to compare to tabulated data that is supposed to be represented by the equation. I want to show that the equation is accurate in relative terms because determining k is not necessary, it's just the accuracy of the exponents that I am interested in.
One way I thought of doing it is dividing Y(x2)/Y(x1) per variable and comparing the jumps as per the equation to the jumps in the equation. Is there a more accurate way of doing this.
Thank you
