Dear rooters,
Fitting that I’m trying to do fails with a message:
Warning in : Abnormal termination of minimization.

I am attaching canvas with the graphs (I am interested mainly in the lower right fit). The fit looks great. Nevertheless…
Could you, please, tell me what can be a problem.
Best regards,
Slava
