Hi, As I am exploring the functions of JMP more and more, here is one I haven't been able to crack yet... I am trying to fit an exponential 3 parameter function through some datapoints that report yield in response to a certain dosage of products. I can get the nonlinear fit of the model, but what I would like to be able to do is to force the fit to start at the response variable for the dosage zero. So if the model is y=a+b*exp(c*x), where x=0. I guess my real question is if you can restrict the model and force it through a given point. Any ideas on how to get this to work?
