4PL fit with covariates

Does anybody know how to do a 4PL non linear model with covariates variables?

Thank a lot,

Florence

Re: 4PL fit with covariates

The 4PLC model is available in the Fit Curve platform. This model, though, does not include any covariates. For your purpose,. you will have to define a custom model as a column formula. It is easy to do. This modeling is fully explained with examples in the chapter about the Nonlinear platform. Select Help > Books > Predictive and Specialized Modeling.

Please post again if you have any further questions.
