defaulting to model = "ZXZ"

[Steviey]

Is there a reason why adam_reg(), engine auto.adam defaults to model = "ZXZ"? According to Ivans book, this translates to 'additive trends only'?

This is the default value in adam(). The additive trend model is more robust than the multiplicative one.

The default values are the same that Ivan selected in his smooth package, "ZXZ" for both adam() and auto_adam(). I can't see any reason to change the default values, honestly.

I think this issue should be closed for the moment.
