The code absolutely does matter, as we need to be confident that it is a correct implementation of the model. To turn your first sentence around, if the code is incorrect than the model doesn't even matter.
I've done my share of implementing statistical models in code and have seen plenty of examples of incorrect code failing to implement the model correctly.

The discussion needs to not be on the code but the quality of the assumptions in their model.

- CrazyStat 5y agoWhy should I care about the assumptions of a model if that's not the model that is implemented, because the code contains errors? Obviously the assumptions of the model are important. But I was responding to a claim that the quality of the code is not important, which is also obviously false. Neither discussion alone is sufficient.
