what is the difference between an inferential and a simple why is an interaction of a data point more robust why is aic higher than simple specification in a model? what is a complex model? why is inference not stable how to make a model simpler how to infer a complex model is a complex model a better model why is there a problem in the complex model why is there an inferential model? what kind of data is needed for a complicated model what does aic indicate what makes a model complicated what is the difference between a simple model and a complex model how to infer a complex model what is the difference between a simple model and a simple model? can a complex model with large datasets be tested without inference can you add interaction to a complex model why is a complicated model not stable a complex model has ________ variables
