Dear Statalist,

I have a twodimensional dataset of two continious variables and want to fit a regression to the data, but I want the outcome to be an s- Curve (or logistic curve). I think it might be like fitting a polynomial to the data, but as mentioned I want to fit an s-curve, which can be expressed by the exponential function. I am aware of the logistic regression, the difference is, that my dependant variable is not binary.

Can anyone help me out?

Thanks,
Sven
