Hi folks, I was trying to implement a simple GARCH(1,1) in IRIS. The model looks like this:

I am getting the following error:
Solution not available. NaN in derivatives of this equation in #1:
'e=v^(0.5)*z;
I could not figure out why I am having this error. What am I missing? You can find the GARCH model files here in case you care to take a look at the code.

Thank you so much!
