Help with fitting
Hello, I have experimental data with (y) and (x) I need to fit them into the following model Log (y/b) = Log (ax /b/1+ax/b) + (-0.22/1+(log ax/b)^2) The result should be a plot with Log y on the y-axis, Log x in the x axis. and the two constants a and b will be the result of the fitting. I tried that in Mathematica, but my problem is that I don't know how to define the function so I can keep (Logy/b) in the left side. Mathematica allows me only to defin a model in the form (y=f(x)) Any help please?
