I am trying to fit concentration (in x-axis) and approach rate (in y-axis) using a logistic equation. The real values of x are [0.5, 2, 5, 9]. Should I fit real_x vs y? I think I saw somewhere that one should use equidistant points (like x = [1,2,3,4]) for fitting. What is your opinion?I am trying to fit concentration (in x-axis) and approach rate (in y-axis) using a logistic equation. The real values of x are [0.5, 2, 5, 9]. Should I fit real_x vs y?
