I can think of several scenarios where zero-inflation is mechanistically plausible, but may or may not be necessary to model in practice. This is important because there are also costs associated to switching to a ZI model: fitting zero-inflated count models is usually much more computationally intensive than fitting a non-inflated count model, and hurdle methods are faster but the zero-inflation parameter can be hard to interpret. | |
