Hello everyone!
I want to create a seasonal arima (3,1,2)x(3,1,2) process with seasonality 24. I use the default optimization algorithm sequential quadratic programming. When I run the code I get the following warning:
Nonlinear inequality contraints are active; standard errors may be inaccurate.
After searching the internet I found out that I can choose a wide range of other optimization algorithms. How can I find out which one is the right one for my problem?
Are there any other possibilities to get rid of the warning?
Thanks a lot!
