It is important to deflate ( remove ) the main effects before estimating the interaction effect . 15. However, this occurred as an interaction effect , and only was predictive for high-status individuals. 16. The theory s other predictions, particularly in terms of critical interaction effects , are less strongly supported. 17. Recent research has begun to examine the empirical evidence for the existence of goods which show these interaction effects . 18. To disentangle contagion from interaction effects , county-specific variables have to be used to instrument foreign returns. 19. However, the second study reported in the same paper found a significant interaction effect of race and condition. 20.
