if the two level and three level are important, can we interpret the two and three level interaction? why does it mean two level interaction is significant what is the difference between two and three level interaction in r what two level interaction is significant if two level interaction is significant, how can lmer interpret? does lmer include if a two level parameter is not significant? is the lmer interaction significant when the two levels contradict one another? can you interpret two-level interaction? how many levels is significant in r why two level interaction is ignored lmer interaction is significant what is the difference between two-level and three-level interaction in r which parameter should not contradict each other in r if two level is m significant, what is it mean which is not significant in lmer if two-level is significant, two-level can't be ignored how do two-level interactions differ? if two level is significant how many ivs can two levels of an interaction be ignored what is the difference between two-level and three-level interaction
