user-defined curve fitting


I would like to fit my data using a specific function y=a*x/(b+x). It seems that this can only be done by programming instead of GUI, could anyone kindly provide a template or direct instruction for doing user-defined curve fitting? Thank you very much for your help!



Look in the curve fitting dialog: Analysis > Curve Fitting, for the 'New Fit Function' button.

a and b are the fit coefficients, x is the independent variable.

Click the 'Help' button (or execute DisplayHelpTopic "curve fitting") for instructions on how to set up a user defined function.

If you run into problems, ask here.

Check out the menu: Analysis --> Curve Fitting, then the "New Fit Function" button on the "Function and Data" tab.
