AIC for self created nonlinear model

Hi,

How can I get AIC values for a self created nonlinear model (by column formula)?

I choose Analyse > Specialized modeling > Nonlinear , I put my formula column as X, the response column as Y, I get convergence. But how can I get AIC values to compare the model with a linear model? Or are there other ways to compare my formula model with a linear one?

Thanks in advance for your help!

Re: AIC for self created nonlinear model

You can calculate the AICc for the continuous response using this formula:

Where n = sample size, p = number of model parameters, and SSE for the fitted model. The log() is the natural logarithm function.

Learn it once, use it forever!
