Very helpful information

Why is causation not important in prediction modelling? Wouldn't the inclusion of potentially spurious factors be problematic when trying to apply the model in other samples?

[@jekamito]

that is why you need external validation for your models. To determine the causality of a factor, you need to know the causal model, which we do not many times. Check Miguel Hernan's lectures on the topic.

@@jekamito Isn't that just implicitly saying we do need to know causal factors, whether they are obtained from external validation or causal modelling.
