which two main factors are negative what is negative effects of the interaction of v2 what is the main interaction term which of the following variables has positive interaction coefficient with the other two main effects if two of the main interaction variables is positive what is the result? is two main effects negative or positive if the two main interactions are negative are the interaction variables v2 positive or negative? why are there two negative main effects on the interaction terms? what is the difference between negative interaction effect and positive interaction effect? what type of interaction is negative or positive? what are negative interactions and interaction effects? which of the following are negative main effects, positive interaction effect, or negative interaction,? which of the following variables has a negative interaction with the interaction term? which of the following is positive or negative interaction and is it negative? is v2 negative for two main effects? what is negative main effects can interaction between variable be positive two effects in a negative interplay negative interaction definition
