Hello.
Please, I need ssome help.
I am trying to obtain the parameters of the Bass model (p, q , m are coefficient of innovation, coefficient of imitation and market potential, respectively) . The message I got was that after 800 iterations convergence was not reached.
The initial parameters were obtained with Excel's Solver. I had the same issue before and I used the program NELREG which gave me same error but I used a script and was able to find convergence. I am sure the same will happen with greatl provided I use proper script.
I thank you in advance for help.
Regards,
