how many interactions in lmer which model requires interaction terms in separate models how many interaction models can interaction terms be used with two models can lmer evaluators evaluate multiple interactions why do interactions need to be included in different models how many interaction terms in interaction modeling how many interaction model how to separate inter-relationships in the same model? what model do you use to model interactions can two model terms be included in two different models? can interactions be used in a different model can interactions be evaluated as separate models which term is used to describe cross-level interactions in a model? can you evaluate interactions in three different models can interactions be evaluated together can a model have three interrelationship are interaction terms in separate models why are interactions in different model? are interacting terms in two separate models
